Up front, I have literally never welded. The makerspace where I'll be building 'the box' does have welding equipment, and the folks there are happy to help, but personally constructing the trailer seems kind of risky given my inexperience.
It seems as though I can buy an 82" x 10' trailer with a single 3500lb axle with brakes for about $1500, and I think I can pay a little extra for a dexter axle, though even reading here hasn't yet made me totally clear on why they're so much preferred. The online site has a number of extra options available that may also serve me well.
As a third alternative, I could, as many do, draw up my own plans and approach a local steel shop and have them put it together for me. I'm not sure how much money this would save, and I'm not sure what issues that might present when it comes to registration in Florida. The same applies to building it myself, of course, but it would avoid some of the danger of my inexperience. I imagine any decent shop could steer me clear of any particularly bad ideas.
Anyone care to weigh in? My budget isn't limitless, but the trailer wouldn't break the bank. I would consider welding a useful skill to be familiar with, if it's something a complete novice could tackle safely. Thanks so much!
