Looking for a 10k lb car hauler with wood deck that will be stored outside. I’ve seen lightly used trailers with way more rust than I’d expect. Brands that Seem well built, are within budget and have features I want include Sure-Trac, Diamond C (20% more than others), Lamar. Won’t be used hard so weathering will be an issue because I’m not going to wear it out with use. Aluminum is at least 50% more, will it last enough longer than steel to consider it?
