I know how you feel. I have a mini van that I am converting into my little weekend adventure van (not full timing...yet). I built the bed/couch platform so it's ready to sleep. I still have a lot of little odds and ends to do to make it more camping ready (like black out curtains and other details) but I do camp in it. A few weeks ago I was going to stay with my sister down by the Galveston area in Texas. She lives just a couple of blocks from the bay. When I arrived she showed me her spare room she set up for me. They mounted a new TV on the wall and she was like..."Look I cleaned all the sheets and it's all ready for you to be comfortable." I told her that's nice, but I'll be sleeping in my van on your driveway. She was like "WHAT?!?!?" I took her outside and showed her my little setup. When her husband got home from work that evening she was like..."Can you believe he is going to sleep in his van on our driveway!!". I took him outside to also show him my setup. After he saw it, he was like..."That's cool! I'd sleep in it too!"
So anyway for the four days I was there I slept in my van. The weather was absolutely perfect! Mid 70's during the days to the high 50's at night. I had a super comfy little bed with memory foam and it was perfect weather for a light sleeping bag. I had my side windows in the back cracked open and I could feel the nice breeze at night. In the mornings I could smell the salt air with the sounds of seagulls and ships passing by in the background. That was some of the best sleep I have had in a long time!!
