Found this on another form. Fire was several years ago.

When we had our fire in Kansas with the GMC I closed all windows and door to starve the fire of Oxygen. Then we ran like (H!!!!) because of full tanks of gas and propane. The fire department had to bring a water pump truck because we were out in the middle of no where. The interior was smoke damaged, the pilot and copilot seat backs melted. What saved us was the ablility to exit the bus quickly. Although Sue got her hand burned it was minor compared to what could have been.
All that was due to an exhust pipe separated just past the Y-pipe coming out of the engine. Fire burned through the floor board as I was driving North on US 54 towards Dodge City, KS.
We now check the exhust system every time before we start out for a trip and every time we make a rest stop I open the engine compartment to make sure we don't have an exhust leak while the engine is running. What ever the result on Randy's fire will be added to my check list. We can't be too complacent when we take our families and our homes on the road.

A very important post, thanks for bringing up the subject. On 73 coaches
with only w wooden floor, I have seen char on the wood over the mufflers
with NO problem in the exhaust system! The 74's had muffler heat shields
and after that the coach had a composite floor structure with the wood the
top material. Burning through all of that on a 78 must have really had a
pile of heat under there. Your plan to smother the fire was brilliant.
The coaches close up so tight the oxygen would be used up fast... kudos on
that one...

My '75 Transmode has a very neat hole burled in the floor just inside of the door. There was an exaust lean that burned its way through the aluminum sheet, the foam insulation and the 3/4" ply-wood. The Hole was about 3" diameter.

My '74 now has steel heat shields under the floor and above any exhaust components. There is an air gap above the steel and then Fiberglass duct board between that air gap and the 1" ply-wood floor.

G'day,

KelvinD has a 1973 without the aluminum sheet and foam and here's how he attacked the problem:
