As many have said aluminum is the way to go. Seems like it's a never ending scrape , prime, and paint revolving rodeo for me. It's a constant attempt to stay ahead of trailer cancer that I hope to eliminate down the road. Priorities in life come first so I keep spot treating for now. I find it true that steel is crap. What's interesting however is comparing steel. I called my buddy to see if my old trailer was holding up, he said it's excellent. The replacement shorlandr is indeed superior vs sc or mfi production.
