Do you have a picture of it installed in a pickup?
I like the idea of the product, I just think that having the knobs mounted on different sides of the box will make mounting it in the cab and looking "integrated" a bit awkward. I have looked at the knobs/valves online and realize that the way the plumbing attaches dictates how they are mounted. I think if the knobs and gauge and switch were all on the same side it would be easier to mount.
What kind of price would the kit minus the enclosure be? I have a '71 F250 Fummins that I would like to install this in but I want the knobs installed in the dash in the factory ash tray hole. I guess my question is, will you offer a "builder" kit with the parts minus the box?
