This turned out very well. A ATV hitch haul rack,my bike rack and parts from a Thule bike rack added for height so bike clears cargo area.Rack fits inside Casita tail lights for clear view. Built with heavy 2" square tubing and braced. You could pull stumps out or hang a deer from this. My welder makes metal art with a plasma cutter and sells these metal nature scenes and put one on the front for a added touch. My Hitch on Casita is welded frame to frame and does not touch the bumper so it's rock solid with the use of a "hitch vise" clamp to take away any wobble.

Please be very careful about your scale weights and weight distribution with this setup.

Putting weight as far back from the axle of a trailer is the very worst thing one can do sway-wise and extra care should be taken to get the balance right.

Weight limits and concerns were part of the build process. My last trailer was also 3500 lbs gross and I had sway issues because it was to light on the tongue. My Casita is very tongue heavy requiring the use of a weight distribution hitch. The weight in back is a good thing and I am good for about 300 lbs there but am carrying only about 100 lbs. It pulls better with the weight on the back and a full fresh water tank.
