I asked the same thing this past year. above is the thread
So far, 3 trips and all great experiences. Karen's shoebox, I mean, the trailer hasn't been a hassle at all. Just be aware that in heavy traffic, someone may try to slide in right behind you to change lanes and not even be aware you are pulling a trailer. You want plenty of lights so it is seen-not just the bike. Someone here said NOT to match the paint as cagers just won't notice the trailer at all.
I added a stern, boat light that telescopes high enough that hopefully a trucker could see in the dark. (all the running lights were 12 inches off the ground). I also added a spoiler light I bought on wingstuff that would typically go on the trunk.
I think it's important to also consider load shifting around a turn. For my trailer, I changed out 6 bolts/nuts that bolted the box to the frame with small eyebolts (on the inside) and added bungy cords to create 6 compartments inside. Along with anti skid matting (used in toolbox drawers) it keeps the gear and bags from moving around. As you are talking tent, I would pay attention to the gear inside and make sure it is secured in some way.
Good luck, use normal precautions as with any trailer but don't overthink it once you are on the road. I forget it's back there now except my rpms are 150 higher at the same highway speed and gas mileage dips to about 4 or 5 miles per gallon.
