While the configuration of the trailers, and setup are different, probably the parts used are similar. I would really like to see one in action being used. There are parts of the system that I know I'm missing, but I know I can do without. There is a solvent tray, tank and pump I don't have, but don't need. There is a larger transfer pump I think was used to filter hydraulic oil for the equipment they were working on. That probably would have more utility in a war zone than on a base. What I would like to see are hoses, and lines being built in a video, or written instruction on what is needed, and how it's done.
A friend came over and took a look at the unit, and asked why don't you just have the hoses you need built by a shop? My son says the same thing, but how much fun is that?
