A custom welding bed is a must for the professional welder on the road. Each welder has their own way of setting up their equipment. Bottles up
Bottles laying down. Hose reals large or small. Goose hitch for hauling 5th wheel trailer. Tool boxes on the bed and under the bed. How about a roll out to set the welder on. Then when it needs serviced just roll it out where all angles of the welder can be reached. All kinds of ideas can be done.
