I've had the Renogy portable suitcase for a couple seasons, and have been very pleased with it. Here in the East we don't necessarily chose to park under trees, we just have trees everywhere! In order to catch photons I end up moving the panel several times a day - no way could I get that type of solar gain with a roof mount system. I find durability/construction good. I also added extra cable to make it more portable. Our previous 'B' only had a single house battery - I could go 5 days without running the genny as long as I didn't run the heater much (power hog blower...). New rig has dual group 27's, so will be that much better off. One selling point is the case Renogy provides - really protects the panels! ST
