That's a pretty cool little rig @lightsplasher! And I'd guess with an A-frame design it it has pretty good height, too. I'm always interested in various pop-ups because we have pretty limited storage space at our house... no real place for anything with any height, so collapsible is kinda important.
Also good point about the mileage you're getting. It all adds up.
We are really enjoying it! I can't wait to go camping again. Having it fold up is a real plus for storage and towing. When it is opened up it is very roomy inside and is easy to move around in. If you store it outside, many of these designs will leak when folded up so you need to get a cover or pay attention to what is going on with the seals more. It is better to store them opened up if they are outside. (The water runs off the roof better, however it can still harm the floor and rot the wood - I purchase a used one the owner replace the floor on) I like to keep them in the garage so that I don't have to worry about water issues, solar damage and plant growth. Water damage can be an issue with any trailer stored outside, they aren't really made all that well for long term weathering imho.
