Not a big fan of using engine compartment air for heat. There is always going to be an odor.
However, no reason at all that copper tube could not be tightly wrapped around the downpipes (behind the exhaust manifold doughnuts). Pump some
coolant through it and to an auxiliary heater core with fan and you've got heat. I'd mount two, in each seat base, and blow the hot air forward.

This in not an uncommon problem with a number of the early coaches, primarily the 1976 and earlier coaches. GMC issued a Dealer Service Technical Bulletin 77-TM-1 dated Feb 1977. The subject was “Cold Weather Driver & Passenger Comfort” and was issued for all motorhomes and transcodes prior to the issue date. The 77 & 78 coach did not appear to have the same issue and both the 77 & 78 chassis that I have driven have not had the cold weather issues. I have driven to Florida and AZ in Dec and January thru some nasty weather and was never cold. I don’t have access to a short cut to the DSTB, so if someone does please post it.
You don’t need to throw a lot of money for a bandaid fix to fix a problem that GMC was aware of and how to fix it. Plug your air leaks and it will be a vast improvement!

I may be on the wrong end of this conversation, but I caught talk of heat for the coach by the driver and passenger. I particularly was interested where they were saying the earlier coaches had a problem with heating.
I have a 74 Glacier and I can't tell you what this thing has gone through with the prior 3 owners but the heating/AC was a basket case when I got her.
A couple years ago I was trying to get heat to the drivers area and starting taking things apart to see why there was only cold air, even when the heat lever was over to full heat....
I found that the cable hold, that screws the plastic tube to the control panel chasis in the dash had broken off so when you moved the heat lever, the entire cable just moved to and from and the heater door didnt open. After I replaced the cable, the heat worked well.... But there was another change that I did too. The POs, well one of them, must have had a vacuum problem because allthe vacuum hoses were cut off, including the vacuum lines for the air vent motors. There was no repairing this, nothing was left. I ended up proping the vents open full time to get air flow into the coach which may have helped with the heat remedy.
If you are having a problem getting heat or air flow, I'd check both of these items. The heat that I get now is quite adequit, far better than when I brought the old girl home for the first time......
