K i just bought a 77 parkland tent trailer. My first camping trailer. Its in very good shape. The frame and flooring are solid. My question is if anyone has extended there frames. I want to extend either in the rear of front so that i can put my quad as i only have an suv. the trailer itself is a 12 footer and im guessing that i want to extend it about 4 feet. any advice would be much appreciated.
