Sorry for the slow reply on this one. I'm up in Canada so my trailer is in storage and under a couple of feet of snow right now. More pictures will have to wait.
As for more info,
The first thing I needed to find was a good solar panel that fit under the tent. I wanted 200W, so I went with 2 - 100W Renolgy compact. These fit well side by side, so I bolted the frames together to make one large panel.
To support the slides and panels I bolted 2 1"x2"x4' solid aluminum to the roof rails. On top of them I used a couple of aluminum 2"x2" angle iron to support the slides. The slides I got from amazon and were 48" good for 500 lbs.
The angle iron, slides and panels have just enough room to slide under the roof rack cross bars. I did not need to remove the tent for install.
For wiring I went strait down to a battery tool box you can see in other threads. I disconnect the wires when traveling and store them in the box. MPPT sits in the bar beside the battery. My electrical system is a bit more in depth and you can see that in another thread.
I can't get any pics now but if you need more info send me a PM.
