All very useful information...it is a standard/short bed truck, and won't be changing that any time soon :)
Mileage is around 83k, and the pin is very close to the axle, not too far off it with the Andersen.
The truck sits very level, and the 5'r is about 1" high in the front due to the height of the truck bed.
I'm thinking bouncing or porpoising comes from old shocks and maybe not enough pin weight.
Not sure if doing anything to the camper would help...like shocks, etc...
Seems I can only add a link to a photo as opposed to attaching one...so can't show a photo of the set-up.
