I rented the 5x8 enclosed Uhaul trailer to move from NY to PA a few years ago (only 150 miles or so, but including bridges and very rough highways in Queens). Don't know what it weighed, but it was full of all my personal belongings, some furniture, tons of tools, a bunch of Jeep parts, a 32" CRT TV, etc and had to total more than 2000lb. It towed great behind my SWB TJ. I did need the hard top to rent it though, and at this point I had a Hidden Hitch receiver and only needed a 2" drop hitch.
Since then I've moved twice more in town and used a friend's 5x10 open trailer. Don't know what it weighed, but the load that included all my tools and some of the furniture loads had to be over 2000lb. The picture below was one of the lighter furniture loads.
Slightly off topic, but I actually had that trailer break loose once when the nut come off the hitch ball. Luckily the trailer was empty, the safety chains did their job, and there were no parked cars or oncoming traffic, but I almost needed new panties. I ended up using a ratchet strap to hold the coupler (with the ball in it and in the hitch, just without the nut to hold the ball in the hitch) to the hitch and limped home a mile or two. Now I check than damn nut every time I put the hitch in the receiver.
I now own a 5x8 open trailer and use an adjustable drop hitch (set to about a 10" drop) and the receiver that's built into my Nate's 4x4 bumper. I haven't loaded it with anything too heavy, but I use it to bring stuff home from Lowes, take yard waste to the recycle center, etc and it works great with the Jeep. It actually tows so well that when it's empty I have to continually check my mirrors to make sure it's still there.
