Don't know how I missed this poll for almost two months.... After all the time I spent working on the plans, building, rethinking, re-building, and all the related changes I had to make because of my design, I certainly feel that I have to put in my $.02. The first feature I deemed necessary for my 4x8 was the A/C. Texas is hot, from April to October (moderate in March and November), and I've known people using the A/C in December as well. Of course, the A/C needs power: a self-contained generator to power it, off the grid, was a must-have (my wife's hobby of Crypto-zoology takes her into the boonies). So far, no major design innovations required in the plans. It was when I did the side layout, and saw that the A/C wouldn't have the needed space to fit on either side (two windows, two doors were decreed by my wife), then the A/C was put into the galley wall. Then came my masterstroke/innovation/overcomplication? that took up so many hours of building and re-working: I decided to make the rear exhaust turn 90 degrees so the hatch could be closed when the A/C is used at night! Three major rebuilds over 6 months, until it worked good enough for Texas heat. As they say on TV- "Don't try this at home!" unless you're one of the following: (a.)an experienced HVAC professional, (b.)willing to spend entire weekends doing something over and over, or (c.)stubborn and determined to the extreme. I wish I was (a), but instead I am (b & c). I have already posted so many times on my A/C tribulations, I will not post any more pictures (other than this)

or links to threads about it. However, I still think about it daily; it's part of my persona now, like a scar-or maybe a beauty mark (beauty is in the eye of the beholder?).
