Jayco Eagle DIY Rear Storage Platform

I have a similar factory fab platform under my Cougar travel trailer. It "glides" in/out on roller bearings. Problems are two fold. It hangs low, limiting ground clearance (but it does help protect my black and grey sewer outlet); and the two rear stab jacks are mounted to it. That means wherever the rack is when the jacks go down is where the rack stays, and any stabilizing pressure on the jacks is pressure on the roller bearing axle not directly on the frame. One of the axles was sheared in two wnen I bought the trailer.
