Yah I get that. It’s more a suggestion if he is looking at a clean slate approach of replacing the tow vehicle. If that is in the cards then it’s a simple straight forward solution for someone wanting extreme off grid capabilities with a trailer truck solution. We do this to a lesser more limited degree towing with an electric SUV.And what will that cost if a solar battery is to expensive?
Just a suggestion. There are lots of ways to do it of course.
