Being a diesel guy at present, it may not be my place to offer any solid advice, however in consideration of the relatively uber light (2000# +) camper and in the interest of better MPG I’d be tempted to lean towards the 3:73…I say this mainly because of the 10 speed tranny (in which you could manage a downshift where needed), and because of the higher torque of the new 7.3.
