Hi Sushidog, I have been thinking the same for a while, it will be really nice to have a way to get out of that situation by yourself, and specially being in the middle of nowhere far away from a tow and remember usually they charge like $ 250 per hour of driving so it can get really expensive and not all the roadside assistance will cover it, if is to far.
what they said here about the tow hitch is true, but I will attach a base straight to the chassis, and check with a heavy rescue truck driver, to get some ideas,.... when they do a really heavy recovery, usually they look for the frame or chassis, axle, so it can be done no problem.
the other thing is , that you are not lifting the whole RV,... but for what i found ( didn’t like the news) you should multiply your gvwr by 1.5. In another site about winching they give you a calculator and when I put 26000. lbs it gave me 39000 to 50000 lbs winch (bad news) because a winch that size will cost a lot and it will be not electric , it will be hydraulic….
but I won't give up yet, because you can use a snatch block to double the line, so a 20000lbs winch or a 25000 lbs winch will work , and some are electric,...
Hope it helps, and I hope you can solve it, if i get any news I will let you know.
Best wishes and keep on Rving...
