Easy.
Borrow a truck that the camper will fit, and use 4 ratchet straps from the jack brackets down to the truck some where.
I've driven 1000's of miles like this with FWC's.
4 good straps, hooked to the truck, and take it easy.
You should be fine.
Back in the days, we drove from Portland, OR to Woodland, CA with a Grandby Model on our Dodge Ram 2500, almost 560 miles, with NO turn buckles attached. :O
Not planned, and not advised!!!! We worked too many hours the week/weekend, were loading 8 campers on trailers at 10pm Sunday night, and forgot turn buckles for the camper on the truck. But the camper didn't fall off. So if you have it strapped down, can't imagine it going any where if you are only going a few miles.
