So, tired to rent a uhaul trailer. I put in the X and the 3 in the uhaul website, it said it was all compatible. It would have been bit over the weight limit, but it let me still make the reservation to pick it up. I when to the pickup site hooked it all up and wait for the store to open, they never opened and I had to get a refund. I ended up getting a 2nd driver to just drive the 3 over to Salt lake.
The model 3 had been wrecked into by a truck and the trunk needed some work, it was still driveable. Thanks for all the advice, I might try and tow it back from Salt Lake in 3 weeks. The question is how strict is the weight limit? What could brake? or is just a issue of limiting range?
