DanM, I mounted the panel there because I like concealed wires. The roof being a fiberglass/rigid insulation/metal sandwich, can't run wires within the ceiling. By mounting it here, I drilled through the roof, and the wires run along the inside if the roof hinge then down the front wall into the space below the dinette seat. I mounted the charge controller next to the inverter. Ran from inverter through existing hole in floor to battery. Was going to just tap battery at inverter, but this one doesnt have 12v lugs like older models. All circuit boards now. The panel itself is mounted on Z brackets. This gives about an inch of airspace beneath the panel. The brackets are mounted with stainless steel screws. I thought I would have to through bolt, but the screws bit and grabbed very tight. I sealed bracket screws and wire penetrations with black solar seal caulk. A roofing caulk. Its a renogy solar panel kit , (100 watt panel, 30amp charge controller, mounting hardware, and cables) bought off amazon for about $185.00. I camped in S. Dakota for a week using battery for lights, radio, propane for fridge and cooking. Battery never drained low fkr the whole trip. I have more install pics, but on my old phone. I will have to find them and post.
