Ummmmmmm...
I think that the hitch is rated for 5000 pounds; but your RV might not be up to all of that...
Get your RV weighed: as it would be set up for a trip. Subtract that amount from the GCVWR, and that'll give you an idea as to how much "room" you've got in your weight allowances.
Example: By the time we got our RV set to go: we had less than 4,000 pounds remaining... We picked up the smallest Toad we could find, and will carry it on a trailer. (2,900 pounds)
