So I'm making a last minute trip to deer hunt tomorrow. Only staying one night, but it's going to be cold. My buddy that normally brings the camper isn't coming so I'll be by myself. I have a drawer system that takes up whole cargo area of my Yukon XL and I really don't want to take it out. I was thinking about sleeping in second row (I'm short 5'6") but I have captains chairs. They fold flat, but a big gap in the middle. I was thinking about getting some plywood and fitting it back there and sleeping on a foam pad or something. Anyone done that? Also, anyone have some ideas on some kind of small heater for interior? I'm going to park in a barn so not worried about dew or precipitation and could prob put small propane heater in there. Any thoughts? I've seen plenty of suburban sleeping setups in the back, but not in the 2nd row.
