IS 5th wheel LEVEL when hitched to truck?
What air pressure are you running in air bags on truck?
5th wheel has a dry weight of 9795# and dry pin weight of 2375# (24% pin weight)
What pin weight do you have with 5vr loaded up camp ready?
Mor/Ryde RPB, Correct Track II, EZ-Flex Equalizer, Lippert Shock Kit on 5vr should provide SMOOTH towing
Issue with chucking could be stiff truck suspension (4X4 Camper/Plow/FX packages) and the wheel base of that F250
F250..10K GVWR
1683# cargo carrying capacity
14,400# max tow.........but you have run out of payload hence the air bags and rough riding
My truck/5vr in signature..........SMOOTH
