I saw the F350 the guy is selling for his new one (which should arrive within four weeks). He maintains them like I do mine - spit shined. As a SRW it only has the 3.55 rear end and is rated for 15,900 fifth wheel max towing or 18,500 for TT with WDC. Payload is 3,614 so marginal on these heavy pin weight beasts but it sure kicks my F150s payload's butt. Not near the duelly which would be 5,117 payload for the Crew that year. What I like about it is the short bed where the DRW Crew is 172.4" WB (vs 156" for his). That would be a pain around even the rural burbs I live in.
In researching more fifth wheels it does become apparent that they are all not balanced the same. Some now shift some weight back more and I see pin weights empty vary by 800+ lbs. or more for 5ers with the same empty weight or very close. I wonder if shifting weight back affects the tow much?
