I forgot to ask: Is your camper wooden or aluminum frame?
About your electrical considerations - I have a few comments / suggestions: I've never heard of your charge controller supplier, nor do I have any idea of the price (I only saw it on the manufacturer's site) but many folks, including myself, like Morningstar, and there are some really good deals out there on PWM controllers right now:

They don't have an actual meter, but they do have a green - yellow - red charge indicator, and meters themselves are cheap..
Also, if you think you'll never need to remove your solar panel (because you don't always park under trees..) then the stick-on Unisolar's are reasonable, while you can still get them, considering there are no mounting issues - they stick on:

I own both a morningstar MPPT controller, and one of the Unisolar 68 watt panels. The controller I have used quite a bit, and it's great, but the panel will be going on my rig shortly, and I have not had time to test it. It's the same one Phoenix (and maybe others) use in their solar kits and many folks seem to like them. The appeal being simplicity of mounting, and very light weight for having to lift up your top. The only thing I don't like about the Unisolar panel is that it has a bit of texture, which I worry will get all kinds of tree-funk on / in it around here. My other camper has 2 aluminum and glass panels. When they get all funky, they are very easy to clean. Since you live out west, maybe not such a concern for you..
Another consideration might be to hook your camper battery to your truck's charging system. I just completed doing that with mine. I used a Magnum Power Smart Combiner:

That way, the battery charges when the truck is running, but when you're stationary the solar kicks in. Down south here, it's hard to rely on solar much, as we always park under trees, as I have discovered with my other camper. It makes me long for Utah, for sure! No problems harvesting as much solar as you want out there!
I LOVE your paint job - you mention rustoleum, were you able to get such a nice finish with rattle-cans? You're making me want to paint...
Keep it up, it's going great!
