I agree with you about towing at 55. The greater efficiency and safety is significant. We make every effort to travel on ‘Blue Highways’ at 55 mph, but trying to get home before the snow had us on I40 where 55 in a 75 or faster pack would just not be safe.So… it seems like the big advantages (plus combining one of these with a vehicle with a charge port in front):
1. Great aerodynamics
2. Regen on hills means more efficiency on hilly roads
3. Can use the trailer battery to extend range
4. Being able to pull in and plug in tow vehicle, disconnect and move the trailer autonomously to keep from blocking the parking lot (or move it to charge it), then hook back up when almost done charging
Great write-up! Thank you! I've been eyeing the Pebble for a couple of years now, and this is encouraging. I have been towing my 16' Airstream Caravel with my 2025 R1S, including a 7200 mile trip end of last summer. I also averaged 1.1 mi/ kWh and stressed quite a bit about range, especially through WY, so the tow-assist would be a huge improvement. I also wondered about charging the Pebble along the way. Hadn't thought about unhitching and self-maneuvering to another charging station. Thanks for answering that. By the way, I LOVE the Pebble lay-out (although I travel by myself...and make my bed obsessively every day) For those who are not fans, there is the option of the Lightship, which has the queen bed in the front. Thanks for a very thorough report!

Good questions. Workaround is that with Tow Assist, its only registering as 5,000 lbs by the R1T.Thanks for this write-up. I am currently towing a 28' Airstream with my R1T, but have been seriously considering the Pebble or Lightship.
You said you tow without a weight distribution hitch. That would certainly simplify hitching and unhitching. But the R1T manual states that you can only tow up to 5,000 lbs with a standard hitch, and the Pebble is 6,800 lbs. Is it safe to tow that load without WDH, and does it affect the truck's warranty?
Everything is safe until it's not. WDH provides a margin or spectrum of added control and therefore safety. You will always be safer with WDH than without unless the trailer is extremely light. I ran one with my 3500# trailer on my Jeeps, since they had super soft suspension and short wheelbase. I don't on the Rivian. With the Pebble, I would 100% use one.Is it safe to tow that load without WDH
Almost nothing does, they'd have to prove that the weight caused an issue. And WDH has nothing to do with pulled weight, it's purely about tongue weight.and does it affect the truck's warranty?
I hope that really is just a joke, since the problem isn't the pull, it's the downward force on the hitch.Workaround is that with Tow Assist, its only registering as 5,000 lbs by the R1T.
Appears so. If you troll this forum w.r.t. trailer weights, and efficiency, the OP is already at a disadvantage comparing tows @ 65 MPH. But eyeballing weight vs. tow, one would expect more like 1.1 Miles per kWh for a trailer this size (1.2 was the rumor long ago @ 55 no Tow Assist), not 1.7 he got (1.8 @ 55 most likely).I'm too lazy to do the math here but I wonder if it really is more efficient than a regular trailer or just offloading some of the losses to the trailer battery.
Since you are over 3000 miles from me I don't think a split ownership arrangement will work.Appears so.

Tangent: Anyone want to split ownership on a preorder ($5k discount) due before Dec 14?
Nope, never an issue for us at all. People are different. I would much rather save the wasted space. We've had multiple RVs and boats with single-entry sleeping areas. One boat was even a cave sleeper, it was fine.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).
