Running furnace while driving

[Fly'n Paws]

Our new 2005 Alpine has a suburban furnace that has stopped working while we're driving. We've always driven with the furnace going in cold months but now it seems to shut off as soon as we hit the hiway. It works just fine when we're parked and it used to work when we were driving. Also, there seems to be an extroidinary amount of outside air coming in the housing area around the furnace and leaking inside the coach through the return vent under the pantry and around the storage drawers. So much air that on the last trip we had to cover the area with a blanket to keep the coach warm. If anyone has encountered this problem and has a potential solution we'd sure appreciate your advice.

I don't drive with the furnace running; don't feel an additional open flame beyond the refer is a good idea.

I have driven with the heat pumps running and the generator on to power them. I feel this is much safer than running with the furnace. It's kind of the opposite of driving with the air conditioner on and the generator running.

Unfortunately heat pumps don't work when it's 10 degrees outside and the wind chill is even colder. Driving with the furnace on is one of those choices people have to make for themselves. Sort of like diesel or gas, which one's for me. Thanks for your input but I still have the problem with the furnace not working while we're driving. Any suggestions on how to FIX the problem will be greatly appreciated.

I have run with the furnace on in cold northern temps for over 10 yrs. without problems. Never had a problem, not much help with your problem. Suggest a Alpine dealer.
