that caravan is superb, suspect trick is for it run same rim n tyre as truck.
looks Oz, seen some guys drag an off road twin axle tin tent across the
outback.
have seen in past where folks with road going monster trucks and commercials

of drop plate on the truck, though with older vehicles american style receiver
drop plates can be used then swapped to higher plates for off road recovery.
