I am use to seeing that with motorhomes I have never seen someone pulling a 5th wheel trailer an have a truck behind it. Though it would be legal to do that in Tn you would need a commercial license in many states to pull a tripple. Would take a pretty big truck to handle a 5th wheel an an S-10 behind it. A one ton with 4.11s or better. I would not try it with my 3/4 ton diesel with 3.73s... Not legal in my state anyway.S-10 might be a tow along vehicle ? see it often enough , Big gas guzzler in front , small gas miser at the rear ........other wise yes , totally insane !
FYI. The tiny car in the back is called a dingy or a toad.
