I may of missed something but I'd say skip the pop up and buy yourself an ancient hard top camper. Way less hassle, not necessarily much more weight, probably about as likely to leek somewhere, but they last forever. Probably cost you about the same too. Spent aproximately 3 to 6 weeks a summer between 1973 and 2011 in a hard shell 50's era camper till we let her go. Upgraded to a slightly larger golden falcon that dates from the 70's a few years back and love it. You can still pitch a tent if you want, but the wife and kids, particularly if you've got little ones, will appreciate the amenities of the the hardtop. And, yes, obviously, everyone loves a 12 gauge, regardless of the situation. Bring two.
