I have a huge list from my hunting days in AK some thoughts
permethrin clothes
head net
thermarest cushion and a ridge rest if youll be near rocks - it might cost more but worth it. you can save money and just use a mil surplus rock pad from a surplus store but i would spend on the thremorest
also a
cabinet shelf liner to keep from sliding off of it in hilly terrain
they also make thermorest seat frames you can fold the cushion and make a nice seat vs bring a separate seat
since its warm, I would get a hammock, better than the ground, also better in the snow w/o tent
small camp chair with the material removed and replaced with two straps (open butt area) for personal business (people always laugh when i bring it, but after a couple days they beg for it)
PLB but if your on a trail prob not needed
neck gator for bugs
radio for each party
golf umbrella- yeah its nice to have in camp when it rains, or if you make a quick stop
water bladder-since you have the room/carry it get a blue water cube form walmart and also a couple knock off camel backs
I have a MSR whisper lite, but since you are driving a
coleman propane stove form walmart and a couple propane bottles from waltmart will work fine- You can also pack a
propane torch tip (like the plumbing kind) and use that.
afa food
MH gets old and texture is bland, I always pack tortillas and then I can us the breakfast MH to make burritos, use some
rice/in beans to make a lunch/dinner burrito or throw on a favoured tuna pack in the tortillas, they dont get smashed like break an pack well
since you have your wife, bring some nutella and throw that on a warm tortilla at your first camp, thank me later.
