I want to mount a NorthStar 13kW tri-fuel generator with a 250 gallon propane tank on a small trailer I can take off-road to provide power for a submersible pump and other equipment at a remote building site. Obviously, it would also serve as emergency backup to whatever other eventual power sources I ultimately develop at that location. Anyone have any plans, layouts, specifications for such a lash-up? Are there any DOT regulations related to securing a propane tank to a trailer if you're going to roll it down a public highway? I spoke with one fellow that recommended welding up a "roll cage" of sorts to protect the valve assembly on the tank in the event of an accident. Any advice, suggestions appreciated.
