To answer the packing question it's just like the way you'd pack your dive gear...Last out / First in. We lay the tanks and dive gear down (except for the regs and computers) then pile everything on top of that in the TV while packing most everything but food in the camper. For springs we normally take only one tank each but if we're down in West Palm Bch., or the Keys or somewhere pretty far from home where we can rent the tanks that's the other option and we don't have to carry the extra weight. If you're packing a tent that's even easier to just throw the tent bag in the back or put the dive bag (BCD's, fins etc) on the roof because if it gets wet so what. Let me know if you have any other questions.
