Adding propane system to bus?

[L.Benjamin]

Hello everyone! My wife and I embarked on this skoolie project beck on June thus year and have run into or first real dilemma.

We want to setup a propane system (ASME tank, running pipe, and getting it inspected). Only problem is, the RV standards book does not clearly identify maximum tank size in gallons or even lbs of propane for an AMSE (they cover DOT cylinders). We want to put a 29 gal propane tank but not sure if that's ok.

Please help.

Ask these guys that make them.

Welcome to the Forum.

From what I've read everything up to 100 lb tank is acceptable so long as proper installation procedures are followed (vertical mount etc.) This may also vary depending on your own state laws.

I believe the Blue Bird Wanderlodges came with 45 gallon tanks if that helps.

They don't cover ASME because you shouldn't be using them. DOT is for traveling on public roads. ASME is for the tank behind your stick and brick house.

FWIW I believe many if not most/all permanently installed motorhome tanks are ASME not DOT.

ASME is the standard that all tanks or pressurized vessels are to be designed constructed and tested to. Including some specifically including federal DOT standards.
Propane tanks,fuel tanks.
Federal DOT is the minimum standard regardless of which state that says what ASME standard the tank is to be built to,how a tank is to be secured into,onto around a vehicle on a federal roadway.
Yor state can add/improve there own rules to the federal standards but they can not be less.
A regular BBQ grill propane cylinder is DOT approved and covered under federal DOT as to how it should be secured.
I have not personally read it but have been told that if you are using the grill cylinders that they have to be disconnected on the road?
I know in NC that I see campers all the time of all types and sizes with double cylinders secured on the tongue with a neat simple idea/solution but I haven't seen to many disconnected.
Good luck

Several years ago there was an accident where a tractor trailer collided with a travel trailer . The propane tanks ignited then the diesel tanks on the tractor. By the time they put the fire out there wasn't anything left of both rigs but the frames and the components. I'd have some kind of reinforced cage not just brackets holding the tanks to the tongue or frame. This happened in Eden NC. I think the laws got stricter due to it.

NFPA rules apply. They'll have all your answers.

That said, Tunnels will be the next factor. Tunnels that drop down (Baltimore MD under the river) you can't carry propane. Tunnels high in the middle (most mountain passes) are OK to transport but must be disconnected. Propane is heavier than air and can collect in the tunnels.
