BB - by now - aren't you sorry you asked here, LOL!
Tough crowd - know *everything*.
They tried to tell Toyota, the Tundra couldn't tow a Space Shttle..;)
Since (I think) you plan on leaving the 5th wheel in one place for extended periods, your current truck should do fine. Some suspension additions (air bags) for load carrying capacity would help....as well as paying attention to the pin weight of the trailers you are considering vs load capacity of your truck.
Besides the load, you *do* have to consider stopping capability as well as towing capability.
Soooooo - go to shows, dealers, etc.
Collect the brochures - beside the floor plans, etc. - compare the specs.
That will help a lot - even if you buy a used trailer.
Good luck..:)
