I would use it for fixing things mostly, like the handlebars on my kids snowmobile cracked yesterday, and welding up something like a stand for my OB out of angle. Hadn't thought of building a trailer per se but I get what you mean. I have a buddy with a MIG so I can get stuff fixed but I always wanted to try to mess around with welding. I don't think I could justify spending much more for what I'd do. I just had a few extra bucks and saw that one marked down. Oh, and it does do gas too.

Maybe I'll shop for a new GPS for the boat instead?
