We live in Florida, so a steel trailer is a lot of work to maintain every other year. I believe any weld could fail if not preped correctly, and or welded at the correct temperature with the correct filler alloy. If the structural design is not correct then stress can fail a weld also. I build my own equipment and take great care to overbuild. I use the "when in doubt- make it stout" philosophy. My Cigarette trailer is now 7 years old, and has about 14 k miles on it. It still looks great, and has never had a failure. The Skater trailer will also last a very long time.

Any coating on aluminum is temporary, just soak it in salt water to remove.

i just looked back at the previous pics of it, the welds do look nice. I had never seen one welded which is why i asked, i suppose maybe its a cost issue when building when aluminum trailers as to why we dont see them more often. Was purely out of curiosity and to maybe enlighten myself, looks good.
