We have considered that! What stops us is we are unsure of the ability of the camper to handle that kind of weight attached to the outer walls.
You’re fortunate to have the ability to pump fuel from your generous capacity — our Ram has only a 28-gallon tank and it’s diesel.
Another thing we kick around is a small off-road capable trailer along the lines of the Tentrax cargo trailer (Tentrax.com), but that would put a crimp in our off-the-pavement agility. We’ve been a couple of places where we had to back and fill to get around some steep back-country hairpin turns and a trailer of *any* size would have been problematic.
Appreciate the suggestion — we’ll keep looking!
