I like the concept, it allows you to continue to use your truck as a truck. Also intrigued by the AT Summit and Atlas. Old Crow has referenced the oft mentioned dust/sealing issues. The big issue for me...having to duck into the camper from the tailgate. I have to do that now with my hi-rise topper and as I get older it is a real pain in the neck...or lower back...literally. If either FWC or AT came up with the same design but with swing open doors (yes, you lose the tailgate) I’d be all over it. There is one other mfg out there that has those doors but for some reason (I can’t recall) I wasn’t overly impressed.
