Nice rig, I always was a fan of those Palomino slide-ins. Hope the star gazing is good down in Quartzite. There's pretty good sky up here but a full moon, tonight, and the temps are producing ice halo.
If you're planning on running a microwave, I'd suggest to look for a bigger pure sine inverter and think about more batteries. Maybe you're running a nice generator and charging system so you can disregard if that's the case.
I use a Xantrex Prowatt SW1000. It runs TV, stereo, and a small 120v dorm fridge. The previous Samlex 600w inverter wouldn't handle the loads. The Xantrex is quiet and doesn't seem to miss a beat.
