What we need to know, going from F150/33' TT to 3/4 Ton FW?

1) It is very ez for a loaded fiver's pin weight to exceed a 3/4 ton truck's GVWR. So you either decide to ignore GVWR and pay attention to GAWR or you restrict available fiver choices or you move to 1 ton.
2) When turning, a fiver cuts inside the truck more than a TT, so take turns wide and slow.
3) When backing, a fiver is slower to react to steering changes, so you will need more room for maneuvering.
