I know there are a couple threads on this forum discussing the payload capacity of these trucks and WDH's (weight distribution hitches). My recommendation is to do some research on here before buying a trailer.
My personal experience with my '11 Outdoorsman is it pulls my 25 ft 5th wheel with ease. My dealer thought I might need air bags also but I never did install them because I didn't have any problems.
That said, hooking on to a bumper vs. a 5th wheel is much different and I think most guys on here with a trailer would recommend a WDH.
Oh yeah, and you gotta post some pictures! Helps those of us that are still waiting
