Hi: I needed the perfect project to justify the purchase of a multi process welder from Harbor Freight and a custom 2" receiver for the back of my Rockwood 2506 tent trailer was it. I wanted to use my existing Kuat 2" receiver bike rack and thought this would be a good solution. Here is what my friend and I came up with and it turned out really good. However, I will say that the sway of the trailer (previously it had none) increased a lot. Nothing dangerous, but too much for my liking. In looking at the pictures, I'm not surprised at all, look at how far the bikes are from the back of the trailer and how high they are. In addition, I need to weigh the tongue weight with and without the bike rack. I suspect I'm taking close to 70 pounds off of the tongue weight due to the single axle acting like a see-saw. I may just need to relegate the receiver to much lighter loads like a cooler or something. We we used common 2" angle iron, 4 foot 2" receiver from eTrailer and various smaller mild steel pieces. We designed it so it wasn't permanent and could be removed. In addition, it is above the axle and pushed back behind the bumper to minimize departure angle scraping.
