A few years ago, travelling on a German autobahn, I saw a Morgan towing a caravan. Just a small classic caravan, probably built from plywood, a bit like the one my grandfather built in the 1950's. I'm not promoting this as a new way to use a Mog, just noting that anything is possible. A small campervan sounds perfect for the mission you've described.
Best not to even look at caravans. Caravaners are out to radicalise as many people as they can. We nearly got caught up in it once ourselves - so lucky to have escaped. They start off talking about the benefits and how friendly it all is to try and lure you into a caravan site. Next thing it's 'would you like to come to our caravan for a drink?' And before you know it you're in a circle of caravaners, naked, throwing a beach ball to each other! Keep well clear!
