The top and bows were custom made by Can-Back when the company was still owned by its founder and located in Azusa CA. The company was sold many years ago and relocated to Arizona. I do not know if they are still operational or whether the current owners would do custom work.
Hey there, I recently purchased your old trailer and tent(in 2020) Just about done modifying it. 3,500lb axle and 2020 Jeep JL wheels and tires. Fabricated a new tongue and lengthened it. Straightened the box and raised the RTT rack. Working on outriggers next. Almost done and then a quick paint job.
