I put a solar panel on my camper, and it's the best thing ever. The battery is always topped off and I never have to plug it into charge.
If you're driving the van daily it's probably not as big of a deal...but if it sits at all the batteries will bleed charge to some degree. They will last longer if they're not allowed to discharge, too. (total life span, I mean)
