Same here, only in the back of my Jeep this past Spring. I tooK; cell phone, carry weapon, 1 gal water, a small folding military stove, instant coffee, note book (the one I always have when I go afield), 2 tin cups, a couple servings of instant oatmeal, TP and a folding chair. Hiked when I got to my spot in a circle so thar I ended back at my ride, slept like a stone (heard coyotes and owls), and in the AM made coffe and oatmeal. Then hiked all day and back to the ride - headed home. It was great. Sorry, I kind of ran on here....
I sleep in the back of the truck. I have a truck cap and I use a 2" thick foam pad I got from the surplus store with a sleeping bag. Instant oatmeal on the one burner stove for breakfast and leftovers from the fridge from home for super.
I have a Coleman one burner stove that works great, it uses the small propane bottles.
If its the same coleman one burner I have then a cardboard box with the front cut out, and a hole in the back for the propane line to go through does a pretty good job on the wind. Just use a box big enough to let the heat dissipate so you don't end up on fire. Fold it up for easy storage when done.
