I have a 4 bike that I decided doesn't work for us this weekend. First time using it, and need something else. I bought it used for $150. I'd sell for $100. I'll get some pics tomorrow for you.
Here is our rack. It just did about 15 miles on the back of the camper down a dirt road… So it’s still super dusty. I realized when I was taking pictures that it can be separated and just be a two bike rack as well. It does not work for us, as the hitch on the back of the trailer is flimsy, Allowing the hitch carrier to bounce up and down as we drive. When the truck would hit a bump, it would be accented at the back of the trailer, and with the weak hitch, the bikes looked like they were on a trampoline. I am going to have to build or buy a different solution for us.
The hitch folds up when not in use.
