I would. You can always add some screws and sealant if it loosens up over time. No matter what it is, it isn't going to just fall apart strewing bits and pieces in your wake.
Thanks everyone. We are still keeping this course in mind. Regarding camper sizes - cozy is a matter of degree! Currently we call 3 camp in a Chevy Astro Van. That is cozy. When Mom is getting the kiddo ready for bed, there isn't room for a 3rd person in the van. Not normally a huge problem, I usually wander off and take photos or tend the fire and sip whiskey, but if the weather were bad, I'd be a grumpy bugger sitting outside while they futzed around.FWIW, I have a 8.5' camper, and I can't imagine having three people crammed in a 6.5' camper. I'd recommend looking at the longer campers, even if you have a 6.5' box truck. If your truck is 5.5', then a shorter camper might be a better plan, it'll just be cozy.
