I have a 2013 26 ft. Grey Wolf that I bought about 6 months ago. I operated the heater for the first time recently and while warm air did enter the camper through a floor level vent (not in the floor, just above floor level at the bottom of the stove), I noticed that the AC (or at least the fan) unit was on the whole time the heater was running. I had a 5th wheel before and it had floor vents so all the warm air entered thru the floor, but my TT has no floor vents. Is that the way this unit is supposed to operate? By using the fan to disperse the warm air throughout the TT? Just wondering.

The "vent" under the stove is the heater intake. There shouldn't be any air blowing out of there.

Is it a dometic unit ? Digital readout ? You "should" have gas heat vents coming from the floor area ( if not on floor, look at the bottom of cabinets and bed frames, or low on walls. The roof mounted AC may have a heat strip also. If you have the digital display, you may be running both gas and electric heatstrip / fan at the same time. Look closely at your digital display. You can select just heat (gas), heat strip ( electric), fan, high / low, etc. Hope this helps !

I had a 2012 Dutchman that you had to turn the fan off on the wall controller.Makes a big difference with it turned off.

You may have to set your thermostat fan adjustment to auto, rather than low or high, to keep AC fan from running. In any case, you should have more than one heat vent in a 26' TT. Jerry

thanks to all. The camper is set up at a hunting location so I can't test your suggestions until this weekend, but I'll try all the recommendations and advise next week when I get back from opening day. Wish me luck!
