Just finished mine to the point that I have taken it out and dragged it around some, and fitted it with most everything we will need when we finally take it out for a weekend.
Mine is a 5 X 10, built using 3/4" ply for the walls, floor and bulkheads. Also have A/C installed, a 9 gallon water tank (empty when I weighed it), and a galley with a camp stove and a small refrigerator. Trailer is built of 2 X 4 steel tube, and has 15" wheels and off road tires. Mattress is a 5" thick memory foam queen.
I pull it with a 2014 Jeep 2 door Wrangler. The whole thing, Jeep & tear, weighs 6200 with the wife and I in the Jeep. The Jeep by itself weighs 4500, which makes the teardrop 1700 pounds. It's a little heavier than I originally estimated, but well within the 2000 pound "tow limit" of my Jeep. I underestimated how much money it would take, too, so there's that!
