OK, I know this isn't a "Jeep" trailer. But it's still pretty cool. I recently took possession of a work trailer from the Rubicon Trail Foundation for Rubicon Trail work projects for the Tahoe side of the trail. It was donated to Friends of the Rubicon and has a dump bed which can either be used via a hydraulic jack under the bed or with compressed air. It will hold about a yard of material. In all there are 6 of these trailers owned by FOTR but this is the only one on the Tahoe side for now. It's rolling on 35" Wranglers.
