I see llnks and recommendations for the FMCA, and Motorhome mag.
Try Remcotowing.. There are many vehicles that can not be towed so long as they are "Automobiles" (Cars or pIck Ups) but which can be easily converted into Trailers (And back to Automobiles) by addition of one or another device that Remco-Towing sells.
For example I used to tow a 1992 Chevy Lumina APV till it "passed on' (Old age) In automobile mode it drove just like any other of it's ilk, in trailer mode you put the trans in PARK of all gears, and towed it with the wheels turning freely,, Epically the right front..
The issue on many vehicles is that without engine power the fluid does not circulate in the tranny, this causes bearings to overheat due to running dry and size up.. Remco also sells a pump that runs on 12vdc and provides the needed fluid to lubricate the bearings.
My preference is for the passive devices (Axle lock for FWD which I used or Drive Shaft Disconnect for a RWD) Because the technologh here is older than I am and the mean time between failures.. I'm not that old yet. But to each his own.
Home is where I park it!
