Currently using and old camp trailer with an ac and generator. It has a good bed and sleeps me warm or cool depending on the need. I just need to rig an outside shower assembly with hot water to make it perfect. If anyone has a DIY shower they recommend-I'm interested. Even a store bought one would be good.
I bought a propane instant heater and rigged it up to a 12 volt pump. It came with a removable shower head. 55 gal barrel of water. This year I put a tee in it and ran hot and cold to a normal shower valve so a person could tame the heat. Turkey season people sure enjoyed taking a good shower and not having to worry about having to use just a trickle of water. It is amazing how many barrels of water a camp can go thru.
In addition to heat/ac and bedding desires I also factor in the added desire to sleep with my wife, and that I enjoy more than a little extra sleep.
For a long time it wasn't hunting unless I was camping also. Mostly duck hunting on Lake O, primitive camping. Now I mostly camp while Turkey hunting, don't Deer hunt much.
Campers can be hot. Tents are cooler. If you can get off the ground on a cot you will be cooler (or bone shaking cold if a front comes through). Sleeping in a hammock is cooler too but Im not used to it. I have used a Redneck AC in a tent during Turkey and it works well.
As far as showers, if its cold I dont need one for a weekend. If its hot Ill take a cold one or jump in the nearest body of water.
