One of the reasons we selected a hardside is that we do a fair amount of stealth or camo camping. See Tioga George's Blog for details. Can't really call it camping, maybe vagabonding or traveling under the radar, as there is nothing outside the truck to indicate any camping. That's the nut: nothing changes shape once you are parked, pull down the shades, and you're in for the night. Truth is we have gotten used to that 240 sq. ft. of living space, know the tight quarters ballet, (also known as the 'belly up, get flatter, pass, and rebound') and were just lucky the day we bought the 165-s that it happen to fit our needs then and well into the future when set up time and effort, and exposure to noise and weather were less desirable.
I'm thinking we could have gotten used to an OUTFITTER! or other high bucks pop-up as time rounds off the edges as you use it, but we're used to what we have and that works for us. YMMV.
IF......I came into a lot of $, I would think mightily toward ordering an XP camper as it has the best of both worlds and a lot of well thought out features. Diesel Appliances? Yep. Aerodynamic? You bet. Just the 'cool' factor is worth something. It has a very slight change of shape, but the shape is so foreign anyway who would know if it has changed shape or not?
I found an 10' Alaskan, hard side pop up, stored inside, in a time warp it looks so unused. The price is right but i have a short bed and this would only work with a long bed with the tailgate down as support for something made in the 1970's. It's pretty heavy. It's still for sale in the Bay Area.
