Since you haven't bought a TC yet you may want to consider that part of your reason for looking at truck campers was getting into tighter spots. We had a series of truck camper softer the year and found that popup 8 or 8.5' that did not hang beyond the back of our 8' truck box worked the best for us. It was only 7' tall and about 7' wide. We ran a standard cab to further the mobility and park ability. We could park nearly anywhere a normal truck could park. Our style was to seldom stay more than one night in the same place and get all our sight seeing and such done before we setup camp. Even when we had full hookups we only connected AC to charge batteries and never dropped the jacks, in fact on our last camper I took the jacks off while it was on the truck so it was easy to setup and take down the camp.
We found that you almost forgot it was on the back and I usually loaded in the Spring and unloaded in the Fall unless I needed the truck to haul something. We stuffed so much in the wheel wells, including an ancillary battery that plugged into the side that it was a bit of a task to take off and get everything packed back in when reloading.
Unfortunately a few years ago my wife's knees would not allow getting in the overhead bunk anymore and we switched to a 19' B camper and it serves most of the same needs our truck camper did as far as easy to park and maneuver in tight spots. We purposely got as low as we could and are now 8' 8". Would have liked a popup B but could not find one when we were looking.
