You and I are on the same wavelength: The 13' Patriot fits me and my life better than the bigger ones. And, when on pavement, I can actually roll the Patriot a few feet myself, more if there's a little downslope. I wish I could say it fits in my garage, but my house is little, too!
I also can get both kayaks on the roof of my volvo xc70 by myself. I just got a labor day campsite because their last open site was too small for anyone else!
I've used xtra strength outdoor mounting tape to put up a tissue dispenser and a little holder for my glasses, and a long, now, narrow holder for headlights and lighters and keys and such. I hung up the paper towel holder near the sink: Use those constantly, and I hang the day's garbage bag, too.
So, it's actually not about space, but about little spaces that only I need, where I need them. It's about convenience, not space. To me, the closet, where I can hang my clothes, is the greatest difference from tenting, right behind the 3 steps to the bathroom in the middle of the night....
My little Puppy makes me happy: I don't want any more space, I don't miss a thing. I haven't even found that the missing screen door is a problem: I made a screen drape, but I don't use it much.
