We are new to HI-lo. We have a 2009 Mojo one of the last few trailers built by them. We had design issues with our rig but found solutions. The door is sensitive to the level at which our rig sits and we found that when we are in a single place for several nights it needs to be re-leveled. The hinge for the up and down had to be re-sealed to stop it from leaking and we had to rig up a way to close the air gap at the back of the trailer along the rear window edge so that road debris wasn't blowing into the rear end and making everything filthy. We put thick insulating foam tape across the upper and lower edge so a seal forms when the top is down.
We have had a lot of cars and trailers and they all seem to have something that needs an adjustment to meet our needs. Creative solutions are all around us and people we have met camping have given us some wonderful solutions for unique problems. The bottom cupboard in our trailer is round so we put a 1x1x1/2 inch board across the bottom...we can now store small bins in the curved area that was useless before.
