Odo is also not as easy to see on newer Teslas, right? It used to be on the drivers screen, but I think all the newer ones need to look in the Trip settings, or the "about" section... (been a long time since I dug into their software, so something may have changed...)
I mean, you're supposed to hook on the loop of metal, what makes you think that hole is an attachment point that would be better than the built in loop? (I have an R1T, so I don't have one of those to examine...)
The whole geometry of the truck would change. Leave the wheels there? bad departure angle. Move the wheels, even worse breakover angle...
Add batteries? probably a fairly significant weight difference, maybe needing stronger wheels and beefier tires, messing up efficiency and payload...
LOTS of driver issues there... Needs to start moving forward before turning wheels, give yourself a longer runway to get moving, maybe add ground clearance if it wasn't already high?
I always tell people 'winter tires are the cheat mode for snow driving' because it makes SO much difference...
Nothing is perfect, but good winter tires make a huge difference in traction.
I can't comment if they'll call it in-spec, but when I was experiencing 'bag sag' I made an appt with the local SC. The night before my appointment I got a software update and excitedly pushed it. Unfortunately this apparently resets all historical data for suspension sag... They looked at it...
