Cheap and easy fix for a loose, rattlin', ill fitting receiver hitch.

I have the same problem, compounded by the 2.5" receiver and insert for 2" hitches. I was thinking about thin sheets of polyethylene for spacers, but aluminum would but even better.

I hauled the pontoon again today...Yay! no clunking when using the shim. We even had to go down a gravel road riddled with potholes.
