I've only towed with longbed trucks and both standard cab and crewcabs plus with SRW and DRW. I have had shortbed trucks towing bumper puull trailers but not 5th wheels. My preference is a longbed, DRW, Crewcab....
Here's why:
> I find the ride is smoother with the longbed especially on highway that were built in sections. The shortbeds get bouncy due to the sections creating an oscillation because the wheelbase is too short.
> More space to carry all the stuff you need or think you need.
> Full sheets of drywall/plywood as well as other stuff when not towing.
Crewcab- more room to securely carry stuff in the backseat. Room for passengers on those sightseeing side trips. Room for pets if you have them.
That's my two cents...
