I'll play odd-man-out and suggest that under some circumstances you'd be fine losing the tailgate. From my point of view (FWC Grandby Shell w/ 16" overhang on a Nissan Titan KingCab) the pros of taking that action include: a de facto 65-lb or so increase in available payload capacity; ability to mount 'stuff' along the underside of the overhang; enabling access to the spare tire hoist that would otherwise be inaccessible with a down tailgate. I can think of no cons from having taken that action in my setup, since I'm a function-over-form guy. Weight distribution of your Grandby's config and options will be the primary factor in determining whether no-tailgate is feasible for you. In my case, I use a 60" strip of angle iron along the lower corner of the camper tensioned with lengths of chain turnbuckled to the truck body to beef up the camper support in this area in lieu of the tailgate. Heavy stuff goes to the front of the camper, always. After 3.5+ years of wandering the West in our rig, no-tailgate seems like a satisfactory setup so far and worth your consideration, as it may or may not be a good fit for you.
