If I calculate 20% of Gvwr on the axles, the Gross axle load should be 9,920 or 4,960 per axle. Isn't this cutting it close. Also, I believe 1,800 payload is quite weak for a fiver this size.
Opinions?
1. What are the GAWR on the Federal Certification Tag? Sum of GAWR plus hitch weight is minimum GVWR for an RV of your vintage to meet Federal Standards for first retail sale.
2. On paper the OEM way is legal and specified in their sales documentation.
3. Safety margins are not "build-in" by most OEM RV builders. In fact -if you like to travel with potable water, more than one battery and LPG in the tanks - you risk being overweight.
4. Part of the reason why tires are a problem on larger RV's -no safety margin -run components at maximum capacity without thought to lifetime -except warranty term.
