About that water...my camper has a 40 gal tank in the rear. Both holding tanks are in the front. That's about 300lb being transferred from back to front. It changes the balance. My camper is just a 23' and I have a pretty heavy duty pickup, but with a smaller pickup and larger tanks, it can change the handling.
