I prefer the portable systems. Most all of our camping is in the Northwest and boondocking so there are always trees. The spots you can park are limited but not where you can set up some portable solar panels. I don't think there is much chance of an animal damaging panels. the truck does charge your battery when traveling. 4-5 minutes for setup is accurate and for me a good trade off to get the extra sun. Theft is always a concern. My system uses flexible panels, from Renogy, mounted on aluminum frames. Very lightweight, no glass. Also I can take them along when not using the camper and charge trolling motor batteries, etc. And no possibility of a roof leak. When I change campers they panels will easily go with me.
