Pebble Flow Electric RV Trailer - My First Journey Towing With R1T

[B&TR1T]

R1T and Pebble Flow - First Journey

We picked up our new Pebble Flow Founders Edition at Pebble HQ in Fremont CA on 11/19/25 and began our indirect journey home to Durango CO. We’re towing with our R1T, dual motor, performance, max pack on 21” Michelin Defender LTX M/S2 tires. This same truck towed our 28’ Airstream for over 14K miles. The single axle Pebble is 24’ 8” LOA, 7’6” width, 6800 lbs GVWR and is equipped with dual electic motors and a 45kWh LFP battery pack. All utilities are electric - no propane. It rolls on 275/70R18 Goodyear Wrangler Workhorse All-season tires. The Pebble requires no WDH or sway bars, and tracked very well in all conditions thus far. A full description can be found at pebblelife.com.


One unique feature of the Pebble is Tow Assist, whereby the motors engage to offset trailer drag. These motors, remotely controlled via the iPad mini, also provide maneuverability around a camp site, driveway etc.

Tow Assist is seamless, switched on and off from the iPad. The Rivian has so much power that relieving it of trailer drag isn’t immediately perceived as a huge difference. It’s more apparent on steep grades or merging onto the interstate. One can observe the difference in efficiency after a bit, and regeneration to the Pebble pack during downgrades or braking is displayed on the Pebble app. alongside solar input. I noted 6.4kW on some long downgrades.

The Pebble has great aerodynamics, with no aircon units on top, minimal vents and recessed solar panels. The Aero Box on the bow (covering the 15,000 BTU heat pump) raises for towing, presenting a clean entry. The R1T was not as sleek on this trip, with two cargo boxes atop the bed, so some efficiency loss there.

Efficiency varies with a number of factors, short run comparisons are not statistically valid, and I realize that these early results are hardly scientific, but do offer a glimpse at the benefit of Tow Assist. Interstate driving is generally my worst efficiency. I tow at 65 mph. and am buffeted by the bow waves of passing semis.

My ‘baseline’ efficiency for comparison was an average 1.1 mi/kWh for our 7500 lb Airstream 28, over 14,000 miles.

The Rivian recalculates trailer weight after every hitch-up and a few miles of towing, rounding to nearest 500 lbs. One can also force a recalculation from the trailer display. Without Tow Assist the Rivian estimated the weight of trailer at 6500 lbs. With Tow Assist the Rivian in motion recalculated the weight of trailer at 5000 lbs.

With Tow assist, a 168 mile run on I40 at 65mph yielded efficiency of 1.76 mi/kWh.

We left Gallup NM after charging at the RAN to 94%.

We left Gallup NM after charging at the RAN to 94%. Having made the run from Holbrook to Gallup without Tow Assist, the navigation system estimated our home arrival SOC at 4%. A bit risky, as there is but one fast charger en route, and that at a GM dealership in Farmington with uncertain availability. I’ve had to stop there with the Airstream, and it’s awkward. We rolled and I activated Tow Assist. I towed at 65 mph, but this time on NM 491 with little traffic. The estimated arrival SOC increased to 26%. No charging stop required! We arrived home after 156 miles and 1200 ft of elevation gain with exactly that 26% SOC, in a brisk 30F.

We look forward to many great trips next year, but now it’s snowing and time for covered winter storage.

Thanks for the detailed write up! We recently had a tour at the Fremont assembly plant. We couldn’t spring for the founder’s edition but decided on the pretty much all the other options and have put down the non-refundable deposit. By the way, what hitch did you use?

It’s too bad Airstream didn’t move forward with production of the eStream, the layout is a no go for me as well. For those of you who have never lived with a bed w/o side access, your partner is fully awake whenever the other one gets in or out (think bathroom in the middle of the night). Interested in your take after a few trips, sure is a neat concept. Keeping my Airstream for now, who knows what future layouts/changes may come though

Your experiences in sleeping may certainly differ from others. Enjoy your Airstream.

Pebble provided a Weigh Safe hitch with my Founders Edition.

Thank you. We are getting the magic pack and other upgrades, so no hitch provided by pebble.
Can you say any details for the hitch such as drop length, model number, etc?
We have the R1T. Again, thank you!

Thanks for the great information! How would you describe storage space in the Pebble compared with your 28' Airstream? I currently have a Globetrotter 27FB, and think the Pebble would be a great replacement, but their online info doesn't show the storage very well.

 

[@joshdance]

I absolutely love the idea of an all electric trailer. We have a small old trailer and I dream of adding panels and converting away from propane etc.

The Pebble is on my list of 'sometime in the future'

The Airstream definitely has more storage. As we prepared our Airstream for sale, I was astonished at the amount of seldom or never used stuff that had accumulated in the trailer, much like a garage. The Pebble has less storage to be sure, but we think that it will suffice for our adventures which sometimes extend for months. We are a couple in our 79’s that travels about 10,000 miles per year.

My biggest concern with these (other than price) is that most of the places I camp I stop at a Rivian-only RAN on the way. Unless Pebble has an agreement with Rivian to allow charging there, this would mean a separate charge stop.

Although the added efficiency of this would mean that a few of the camping trips I take would no longer need any charge stop along the way, and/or would give me the range to reach an EA.

But our most common camping trip, which doesn't allow charging at the campground, has only Rivian-only-RAN and Tesla-only-Supercharger within reasonable distance of the campground - so the Pebble wouldn't be able to charge at either. (Although as "a trailer", it *could* charge at the campground, since it's just "plugging in a trailer.")

We have an "all electric" now - just without the fanciness (or price tag) of the Pebble.

A 2018 NüCamp T@B 400. From the factory, the only uses of propane are the propane cooktop and the dual-fuel combo cabin/hot-water heater. Which has a 120V AC mode. So when plugged in to my Rivian, the only "propane-only" feature is the cooktop. So I just use an induction cooktop.

We bought the camper used in 2023. The propane tank was empty when we bought it, and I've never filled it.

My biggest concern with these (other than price) is that most of the places I camp I stop at a Rivian-only RAN on the way. Unless Pebble has an agreement with Rivian to allow charging there, this would mean a separate charge stop.

To be fair, there are only 11 remaining RAN sites that are Rivian-exclusive; Rivian has converted almost all of the sites to hardware that supports all vehicles. What you describe is a short-term temporary situation that only affects a fraction of the country. And chances are that will be fixed before you actually get your Pebble, since there are very few on the road right now.

But our most common camping trip, which doesn't allow charging at the campground, has only Rivian-only-RAN and Tesla-only-Supercharger within reasonable distance of the campground - so the Pebble wouldn't be able to charge at either. (Although as "a trailer", it *could* charge at the campground, since it's just "plugging in a trailer.")

There is no problem charging the Pebble at any campground with a hookup - it's a trailer, and that's why you're paying for the hookup. And they can't prevent you from then plugging your Rivian into your Pebble to L2 charge from the Pebble ... if you really need it.

I have only encountered one non-KOA campground that forbids EV charging. I have never had a problem at any state park.

But again, you can tow-charge the Pebble while driving, so you can "fill up" your Pebble on your way to the campsite. You should be able to boondock for about a week with the power in the Pebble battery.

Disappointingly, Miss Go Electric’s latest (yesterday) YouTube review (albeit pulled by a CyberTruck) of a production Pebble suggests substantially shorter boondock battery duration. I can live with that, but others might see it differently.

I love the idea of electric tow assist, but I can’t stand commercial or established campgrounds and almost exclusively take our off-road trailer to campsites on public land usually only accessible by high clearance trailers built for difficult terrain. Pebble looks like it would bottom out on pretty much any of the places I like to go. Would be awesome if someone would make an off-road capable camper with electric tow assist but I suspect the extra weight would make it a dangerous pig on sketchy terrain.

 

[JamuJoe]

Battery SOC while boondocking will be affected by usage and solar production. Using the HVAC consumes a lot of kW. Best to realize that you are camping, despite the nice accommodations, and manage both power and water carefully. Black water is always our limiting factor in extended boondocking.

There’s your opportunity for design of a new trailer! That’s basically what the founder of Pebble did after taking his family camping in an Airstream during COVID. I share your preferences, though perhaps not quite as rough. My Pebble will spend more time off pavement than in commercial parks, which we reserve for ’recharge, dump & fill’ en route. Actually, the battery placement and weight makes for a low center of gravity, and ground clearance and departure angle are pretty good for a travel trailer.

Disappointingly, Miss Go Electric’s latest (yesterday) YouTube review (albeit pulled by a CyberTruck) of a production Pebble suggests substantially shorter boondock battery duration.

I thought this was a very thorough and good review - really the best info I've seen in one place about the Pebble Flow. I do like the way she went back and added corrections at several places in the video when what she said on her first take was slightly inaccurate. Many people who do reviews fail to make these corrections, which then persist as glaring errors for those who know and as misleading information to those who don't.

As far as battery usage, I think the proper comparison would be to a non-electric travel trailer when boodocking. Apples to Apples. It may seem disappointingly short if you're running everything, but that's not how you would boondock - boondocking always involves paying attention to resource usage, and not just treating everything as if you were plugged in at a KOA. Her numbers aren't wrong, but the implied conclusion is that you can't stay out very long. However with the Pebble I think you can actually stay out *longer* and with *more* capability (HAVC/electric use) than a typical travel trailer.

With a non-electric (e.g. propane + very small battery) trailer, you CAN'T be using the A/C and microwave and refrigerator and water heater all the time unless you're plugged in. And if you're using your 2 car batteries (in a non-electric trailer) to power things, there's no way you're going to get more than a few hours of use out of them. And propane tanks run dry after not too long if you're running the heater all the time. And your solar to recharge those batteries is only going to be about 1/5 for what the Pebble Flow has.

So in reality I would say you can spend way more time off-grid with the Pebble Flow than you can with say an airstream of the same size, IF you are doing the same things with both trailers (heating, cooling, cooking, microwave, lighting, using computers, etc.)

Black water is always our limiting factor in extended boondocking.

And I think that's also the real limit with the Pebble Flow too - it's been raised as a concern because of the size of the blackwater tank, but with the macerator it's not really a gallon-to-gallon comparison.
