Here is my real world experience
2007 Dodge 3500 SRW QC LB 5.9L 48re 4:10 (scaled weight 7980#)
2007 HH II 5th wheel........(Scaled weight 13,783#)
Wet pin at 22% for 2980# on rear axle and 150# added to front axle (hitch set 2" froward of centerline)
Over on trucks GVWR
At trucks RAWR
Under rear tire max load ratings
Great towing combo.....towed weekly for 7 yrs FT
Stable, no 'white knuckle rides', no 'dang I wish I had a dually moments' (had duallies in past so I know the difference). No issues.
Had an Exhaust Brake installed (US Gear) that in tow/haul mode would hold 55 mph on downgrades of mtns roads.
5.9L would Purrr holding 62 mph in cruise control going up 6% Grades (21,763# combined)
So YES...a 3500 SRW is very good towing platform for 14K 5th wheel
