Basement Air and Heat?
2000 Itasca has basement air and heat and also gas heat. I use to flipped on the generator and set the elect heat and all was warm. But this morning I flipped on the generator and the electric heat and the gas heat comes on and the panel blinks the letters "diff" and only the gas heat works?

If it works like our basement air the electric heat will only work for a couple of degrees. If you set it for say ten degrees above the room temp it will automatically run the gas furnace. What I do if I don't want the gas to run is set it about two degrees above the room temp on the thermostat and after it reaches that do it again until it is warm enough.
Someone told us the electric heat is on those units is "just to take the chill off".

Yep, your set temp is 5 degrees or more than the actual temp so gas furnace will run with the heat pump until set temp is reached. Once temp is reached, only the heat pump will cycle. When we had our Journey (8 yrs) we thought the heat pump did a better job of heating the coach than it did cooling the coach in hot weather.

So the basement air is a heat pump?

Yes, and I find that when the outside temp gets down around 40* the heat pump won't work and the gas furnace kicks in. However, with our 36' coach we find it to be comfortable either heating or cooling the coach.

As mentioned the 5 degrees difference will initiate both Gas furnace and heat pump. I have found the heat pump takes a bit to warm up in cool weather just as the AC takes a bit to cool down in hot weather.. If the heat pump is not warming at all check your breakers and starter capacitors.

My basement heat pump works down to 33° outside temp sometimes. At other times it's 35° or 39°. I think humidity has something to do with it.

Heat pump is sometime mistakenly called electric heat
It is a/c with a reversing valve and electronics to make it work.
So it is all in one unit. It only works to around 40 degree outside temp. Residential heat pumps have additional electrical coils that kick in below 40 degrees to take over in colder weather. MH don't usually have the back up coils but use a gas furnace to achieve the same result.

Basement air/Heat unit
Contact Coleman-Mach, they have a different thermostat available that will make the unit operate better.

Is it any better than the True Air 6636-345 most of the Coleman heat pumps have? We have replaced ours but with the newest model at the time a couple of years ago.

Yeah, like to see some documentation on the "better" one. Just what is better?

If you call colemen-Mach they have a thermostat that does not "time out" when you keep asking for more heat
