Sticker shock
I removed and sold an aluminum full length Hannibal rack and an AutoHome Columbus hard shell RTT to pay for almost half the price of my CAMPTEQ top, and I had paid about $4500 for my previous setup. But the value that the new setup adds is - for me - almost impossible to put a price on: I gain a full length roof rack that I can actually carry something on (the AutoHome took up the entire footprint of the Hannibal rack, my new top is bare, super strong and has Mac's Tie Down rails full length on all 4 sides. My wife and I can enter and exit the tent's bed from both the exterior of the truck *and the interior* - with the from-the-interior option a huge bonus in very harsh weather or if we're in a sketchy area. We can stand up inside the truck to cook in bad weather, or eat inside due to the rear headroom. We could sleep two up and two down if we had small kids along. And I parked in the underground garage in Flagstaff Monday - with 33" tires and a 2" lift the truck is under 7' - it was almost a foot taller before. And my fuel mileage has increased by 3-4 mpg without the huge air dam of the RTT-on-a-rack.
I'm a contractor and good with a jigsaw, and cutting out the rear hole in the roof took me less than an hour. Eric cut the headliner and we rolled bulb weatherstripping onto the cut edge of the roof to capture the headliner - the same bulb weatherstripping he uses as a gasket along the bottom edge of the top (the clamps that grab the rain gutter, when tightened, compress the weatherstripping.
