When I was doing courier work, I asked dispatch there about pulling a trailer. At the time, I had a Ford E-150 and the trailer would have given room for more freight. They said no. They really wanted at least a box truck, I eventually bought the Sprinter as a halfway-point. I couldn't park the box truck in my neighborhood and that would have required me to have two vehicles--- and the company I worked for then wasn't paying that kind of money.
The camper-trailer requires quite a bit of maintenance, wheel bearings have already been mentioned. If the trailer is over a certain size, brakes have to be inspected. Trailer lights--- what a nightmare, don't get me started. Then too, these trailers are usually meant to be used only occasionally. I don't know if they fare well if you use them every day, putting several thousand miles on every week.
FWIW, I've owned and maintained a boat trailer. Of course it's different than a camper, you're not ordinarily backing a camper into a lake. Still, the issues of bearings, brakes and lights just don't go away that easily on any of these sport-trailers. You will have to keep up with more maintenance with these things.
Add-on: Towing a trailer adds a bit of work at the pickup-delivery and this has to be thought of. You have to disconnect the electric harness, go through the procedure to drop the trailer and move it to the side. If your hitch sticks out, you may have to pull the pin and remove it and put it to one side. Once you're finished loading/unloading you have to reverse the procedure. Re-attach the hitch to the receiver, drop the tongue on the ball, re-connect the safety chains, re-connect the wiring, check lights and possibly brakes--- just messing with the trailer adds a fair amount of work and time, and frankly it may be time you don't have much of. Having to do this before a weekend camping trip might not be noticeable-- I never thought much about it when towing the boat-- but when you have to do this several times a week it gets old fast. Trust me on this.
