SWR 5th wheel towing

We just stepped up to a 36' 3" fifth wheel on our Ford F-350 SRW Diesel, crew cab, short bed. 10,780 dry, 12,660 loaded ready to camp (full fresh water tank), with 2440 pin weight. I'm comfortable because we installed 6000 lb. axles with disc brakes. But that is it--I would not be comfortable with any more weight even though Ford says we are good for a 14,500 fifth wheel. We are just below the rear axle rating and tire rating--so OK, but no room to spare. SRW is going to save money on tires and initial cost. If looking at longer, heavier, or toy hauler trailers, MHO is one is in dually territory. Toy haulers tend to be nose heavy to allow for the heavy toys in the rear, and really cry out for dually. I was honestly surprised how close we got to our weight limits on axle and tires after we got this trailer. In terms of handling, the SRW crew cab short bed handles this trailer just fine--comfortable in emergency moves, and the disc brakes will stop a freight train after a short delay to build pressure. Our trailer has dimples that allow for tight turns without bumping the cab, so short bed is not a problem, although we have a slider hitch form the prior trailers.
