Hi BobBaron, BigBaron here! LOL
Either vehicle would be fine. Period. The VW will be less expensive to maintain IF you get the diesel. Do not get the gas engine what ever you do. It doesn't have enough torque. John777 got a steal on a Porsche Cayenne Turbo, so if you look around you might get lucky too.
As to the wheelbase issue, class 8 rigs sure are short to be pulling around a 40' trailer then, aren't they? Ever heard of guys with short wheelbase duallys pulling huge trailers? About the same wheelbase... I used to be one of them pulling around a JLG lift.
I have done a ton of research on both the Hensley and ProPride hitches-even to go so far as to examine the actual design drawings and the patents.
My choice? Hensley. I'll PM you why...
CanAm's hitch mods pass my mechanical engineering/Porsche tech smell test. So much so that I'm copying them on my hitch. I'd have CanAm do it but the shipping to Korea is a little steep.
If you can get the automatic air shocks on the VW remember they don't do the same thing as a WDH. You hitch up the trailer with the car running, and unhitch with the car off.
There are a ton of picture on my photobucket, so have a look around...
I hope this helps!
