Place your tent trailer. Where you put your tent trailer is very important. Once you reach the campground you'll most likely have an assigned campsite. Before you unhook the trailer, scout out your campsite and figure out where the most level spot is. Take in to consideration which way you want the camper door to face. Think in terms of creating a semi-private compound with your tent trailer as one divider.
Level the camper. Most pop ups, unless they are really old, have some time of small level attached somewhere on the tent trailer. Once you've figured out the general place you want to put the camper, place your leveling blocks under the camper tires. Then you should be able to gradually move the camper around on the leveling blocks to get the pop up as close to level as possible. Once you have it level, make sure that you chock the wheels so that the trailer won't move. Once you've put down the front support, you can unhook the camper from your vehicle.
Raise the roof. Tent trailers generally have an internal chuck that needs to be turned with the handle that came with it. Some of the newer pop ups have an electric system that will raise the roof at the push of a button. One thing to remember: if it's an older pop up, don't turn the internal mechanism too fast. You wouldn't want to throw your cables and not be able to raise up the camper top.
Pull out the beds and attach the canopy. This is a fairly easy step. But when you pull the bed check to make sure that the canopy is away from the guide rails for the beds. Getting the canopy or screening caught in the guide rails can rip the canopy, and then you've got real trouble. Once you've pulled out the beds, you can attach the canopy and affix the external bed supports.
Fit your door and put up your internal supports. Basically the exterior work should be done. Now all you need to do is bring down the door (if necessary) and put it in place. Then you'll want to put up any internal canopy supports if you have them. Now you're ready to have fun.
