hard side camper like to drive? (cross winds, handling)

For rolling down the highway and using developed parks it would be hard to beat a hardwall with a basement on a dually. Rock steady. Only way to tell if the wind is blowing is to watch the trees.
Me personally, I would go non slide and a fiberglass clam shell construction...Bigfoot or Northern Lite. I wouldn't completely rule out a Cirrus though.
