Camping in the heat is hard to overcome. The one I purchased has a canvas outer layer that endured hours of rain with no problem. If hot, I can zip the canvas down and be covered by what amounts to a mosquito net. I'm usually in altitude where heat isn't an issue but a mosquito net and skivys is about as cool as I can imagine.
I was hoping you were about to introduce me to some magical technique or item that would solve this problem!
What I would like is to be able to take some long road trips and just get a good rest in the 4r to save on hotel costs. I can do it fine, but my wife is really not into the "roughing it" thing, at least some fresh air and coolness.
Hotel costs really take up a lot of a travel budget, all for nothing more than some quick shut eye and possibly a shower, but wow, that is some valuable stuff when needing it!
I am planning for my great Alaskan road trip for next year, so maybe it will be a bit cooler once hitting the Yellowstone/Glacier NP area and further.
