I'm in the design process of my trailer build. I want to mount a Expedition RTT on top of my trailer in the same concept as the Campa trailers where the tent sits on the trailer lid then can be telescoped up 3ft on 4 posts and locked in place. I'm thinking of using 2" square stock then inserting a smaller stock and repeating this a 3rd time till I reach my desired height then locking it with a pin in each section . I'm not sure if something already exists . Thanks for any input. Sorry if sound crazy LOL.
