This is a 12' Welding Trailer. It is completely custom. The Miller Bobcat 250 is elevated to allow for more air to get around the welder. It also allows you to store metal under the welder. It has a Oxy Acetylene Torch Racks, RKI huge storage box, and Montezuma tool box. This trailer also has a Puma portable air compressor. You might say this is more of a Portable Service Unit. It is also equipped with 4 receiver tubes to allow further customization(vice, chop saw stand, or work bench). This is the 4th welding trailer I have had the opportunity to build. I think it might be the best.
