What diameter propane feed?

[roach711]

I'll be feeding 4 appliances:

Atwood 16,000 btu furnace
Atwood 6 gal water heater
Amana 3 burner range w/oven
Norcold n300 3 way refrig (2.7 cu ft)

I'll have two 20lb bottles in the back of the bus in a sealed and vented box and will need to run about 15' of supply hose or pipe in a chase along the inside corner of the bus. My present plan is to use a 15' 3/8" rubber propane hose that will run direct from the regulator to my cobbled up distribution manifold and from there run 3/8" rubber extension hoses to each appliance.

Question is, will that 3/8" hose be enough to feed all 4 of those appliances?

My next choices would be 1/2" soft copper tubing or (failing that) 1/2" black pipe. I like the rubber hose for its vibration resistance and ease of installation but the other two are doable too.

Thanx All!

Thanx Smitty. I'd seen the tables in the first link but couldn't make heads or tails of them, but the Firelogs.com link is very easy to understand.

I looked yesterday around and saw a 3/8", 12 foot long hose that is rated at 75,000 btu. I figure that at most I'd be using 40,000 with everything running so it looks like the 3/8" ID rubber hose will work for me.

Yeah, I'm looking closely at the safety aspect. Long ago I was nearly suffocated by a torpedo heater with the wrong fuel in it and while I can think of worse ways to check out, I don't want to do it *just now*. lol

My *current* plan is to run three plastic conduits down the side of the bus. One to house the propane hose and one each for AC and DC wiring. I just picked up my CO2 and propane detectors too.
