Wow, that's a big inverter and might be a little overkill. I was just over at Northern Arizona Wind & Sun's forum site doing a little research and ran into your posts, funny, great minds think alike....:B
I'd have to say you've got a little delimma on your hands with the battery bank. It will be interesting to see how you'll go about solving that issue. Personally, I think you're a little light on the battery bank size especially for the size array and loads your planning but I'm far from an expert in this field.
Be on the lookout for CrazyCooter on this forum, Tony has a big PV system on his rig and is a top-notch fabricator with a lot of knowledge. If you can get him to chime in it would be a real plus in your favor.
Balancing of the battery bank was a huge issue with me and I took every effort to make that right with very good results. The bank is balanced prefectly. I went with 260 AH Crown 6VDC GC2's. That's another thing I'd change if I had it to do again but again, I'd be up at 24VDC too.
My walls will end up at 3.25" thick when complete and the ceiling will be just over 4". To me, this is one area that needs close attention as if the shell is highly insulated and air tight, the energy inputs for keeping a comfortable enviroment will be minimal. One of the things I'm doing in the living quarters is installing a 'thermal break'. This is due to the highly conductive nature of the metal framing. This will be even a bigger issue on your rig due the conductive properties of the aluminum siding.
This was another reason for the FRP as it's very non-conductive in nature.
I'm rolling with
Motion Windows, awesome warranty (lifetime on dual pane) and very competive pricing. I think they're the best in the industry.
