I have a 1973 26', and going up highway 80 to Truckee my floor caught fire
and burned through. We dumped half a gallon of water on it, and that put it
out.
Looks like last time for the cookie sheet mod. I have headers and the
original two forward mufflers. I don't think a muffler failed, as the coach
didn't get louder. The floor is burned in roughly a football sized and
shaped area over the rear of the muffler.
Right now, I'm parked on the shoulder of I-80 outside of Truckee. I'm
inclined to continue slowly into Truckee while my passenger dribbles water
on the burned spot, get some cookie sheets, and see what can be kludged
together.
How dumb is that? If I can limp a bit further, I'll have a week and help to
get it all taken care of, vs stuck on the side of the road.
Thanks,
Ron

I-80 eastbound from Auburn to Truckee is a very tough climb. I have done it many times but only once in a GMC. The engine will be running flat out and rejecting A LOT of heat during the climb. Get a fire extinguisher and inspect for embers in the wood that could smolder for a long time. Also check your cooling system when it has cooled off, as you can boil off a lot of coolant on that hill if your cooling system is not perfect. I'd also look for an exhaust leak that might have caused the hog spot in the floor.

Well, made it out of the hills, and I have cookie sheets to do the fix
with.
I'm soon off the internet for a week, my apologies for not responding to
any other messages.
Thanks
Ron

Been there, had that happen in a 78 GMC with the original aluminum on the bottom side of the floor. I now have a heat shield above the exhaust system. It's has a 1 inch space between the shield, and floor. Also replaced the heat shield between the gas tanks, and tail pipe that's in the frame rail. There is a way to fix the burned area without replacing the entire floor panel that is as strong as it was. Bob Dunahugh 78 Royale.
