Once I have established that I have an acceptable and understandable choice, I will go looking for a matching fifth wheel. Don't want to buy the truck first.
Definitely, if you can afford it, diesel is the way to go.
My 3500HD has both the exhaust brake and StabiliTrak, where the 2500HD didn't have either.
The exhaust brake along with the Allison transmission's grade brake is excellent.
And the StabiliTrak along with 4x4 performs great in the snow. The StabiliTrak feature keeps the truck from fish-tailing when on snow covered roads.
Pay close attention to trailer's GVWR and estimated loaded weights when picking out your matching fifth wheel.
My 3500HD SRW short bed is very close to weight limits on the truck's GVWR and Rear GAWR with my trailer loaded based on measured weights from a CAT scale.
Probably would have been better off going with a DRW, but didn't want the DRW because of using the truck as my daily drive vehicle. Just my personal preference.
I'm not sure if a 3500HD long bed has a different GVWR or Rear GAWR then the short bed.
Though the advantage of a long bed is you don't need a FW slider hitch.
