Lots of good discussion here. The boxes that I make are aimed at the adventurous DIYer. The install takes enough cutting, grinding, drilling, and thoughtful layout that most will feel satisfied with their time put into that. By the time an average consumer sources all the material, rivets, screws or otherwise fabricobbles six sides of a box together you could have a box for a couple of tanks of fuel for your van.
Will a DIY box be weatherproof, durable, corrosion resistant? YMMV. My original box has been hanging under my 2003 e350 EB for over 150,000 miles. My current welds are a lot more refined than my original work, but I still see my first few boxes outliving the steel van bodies they are bolted to.
Shoot me a PM if you are interested in one. Itís a side hustle for me building them, but I do enjoy doing it and I feel like I provide a fair price for what you are getting.
