The hitch loading on an RV fifth wheel hitch is designed to be between 10% and 15% of overall trailer weight. This is determind by trailer design and axle placement. In the Tractor trailer world they can move the trailer axles, The fifth wheel hitch location and plan the loading to achive the goal of roughly 1/2 trailer weight or less on the hitch.
