I didn't want to permanently mount PV panels so opted for 2-120w flexible panels for their thinner & lighter form factor (trailer); albeit at less efficiency and slightly higher cost-per-watt.
Solar for when the trailer (or spressoWAGON using my old 60w Powerfilm foldable panel) sits for more than a couple days without engine run. And alternator for when we're on the move.
