As has been stated here often, select the camper then buy the truck to carry it. In your case, you will need to reserve payload for the tongue weight of your trailer and as noted, the hitch and extension to get past the TC bumper will add weight. The issue of daily driver throws a kink in the mix. IMHO you will not end up with a nimble daily driver if you properly size your truck to carry a single slide TC and tow a 5klbs boat/trailer. There are a lot of variables to consider: diesel or gas, two wheel or four wheel drive, single, extended or crew cab, manual or automatic transmission...
