I do a lot of military truck recoveries and have experience doing stuff like this and my advice is don't do it. Have it towed. You will save yourself a lot,of heartache and a potential disaster.
A 1 ton truck is nowhere near capable of stopping 14,000lbs of RV . When I tow, I use a military grade towbar rated at 40,000lb pounds.
Also most if not all states, it is illegal to flat tow an unregistered or unissued Vehichle . I usually put a temp or dealer tag on the stuff I tow.
Register it first and put triple a platinum RV coverage on it , wait a week and call them.
I'm gonna move this thread to the 270 forum. This section is for people broken down and in need of emergency help as the thread emails the staff directly when someone posts here.
Heed my advice. Been around the block a few times.
