has no one mentioned HTFU FQ 
get a canopy on the back put in a raised section in the back and put storage draws and in one have a portable sink and stove top that slides out
on top of that just put a swag and sleep in that and you can roll that up when you need extra storage.
Actually, I was the one that raised that point. This whole oddessy started with the idea of me spending summers as a campground host at NPs and NFs in bear country. Me, I'm happy with a big (93 sq foot and 74" tall) $600 tent from North Face. Its big enough for a nice cot and some camp furniture that would make it liveable for 2-3 months. As for bears? Thats why I bought the riot gun, I just can't mention that bit to the NPS.

They want a hard side, and honestly, for that amount of time, it would be comfier. Still, the large tent is good enough for me and I could be good to go for about $1k with all the chairs, cots, milk carton dressers and tables you'd need to live pretty plush by my normal camping standards. Yeah it sucks to run 100 yards to the head in the rain, but thats only if I'm taking a dump at 3am. The rest of the time, no worries. Honestly, a couple of $10 wally world chairs, a few milk cartons, a couple of pieces of plywood plus big cot, stove, battery powered lanterns...what more do you need?
