We are headed on a cross country trip in three weeks and I've been trying to find a decent RV cargo rack that attaches to the hitch so we can store our extra gas can OUTSIDE the RV. All the reviews I read have my head spinning. Every one seems to have wobble issues, rust issues, mesh bottom not welded sufficiently, etc. regardless of the cost. Does anyone have any suggestions or experience you'd like to share with a damsel in distress? Thanks!
