Newbie with a 2019 Minnie Winnie 2455BHS

2019 Minnie Winnie 2455bhs. Just bought and took for a short trip locally to see how everything works. It was chilly one night so I put the heat on but no warm air came out of floor vents and it seems like the ac was going. The readout indicated heat not cold so no clue. Looked on line and one person said the heat ducts under camper were never attached. Haven’t looked since we just got home and have to deal with backed up septic from hubby’s long haired 19yo daughter! Love the camper though!

If this is a new rodeo for you, there may be room for confusion as RV furnaces work far different than at home!
Step one for home, the fire lights and finally the blower but in RV the blower comes on first and make air flow. When that good air flow is sensed by what is call a "sail switch" , then a timing process starts before the gas valve is turned on and the gas lit. Finally after a bit of cold to cold air blowiing around, you get warm air!
There are a number of safety reasons for this difference but it does leave some room for confusion on what to expect and we may shut it down before the process works it's magic OR there may be a true problem.
Since you mention the dog and hair?
One of things which can happen is the sail on the sail switch gets hung up with a hair ball!

Lots of different shapes, etc of sail switch but the idea is a micro switch with thins big "sail" that moves with the airflow and pushes on the little black button of the switch.

You can see how dog hair can stick on the sail? But before panic and saying that is true, try to think back and review if it might also just be not waiting long enough?
I can vouch for it seeming to take FOREVER for the heat to get there when you wake up cold and it sends you cold air! Probably less than a full minute but it feels like forever!

Sorry I skipped to dog hair instead of daughter hair but it works the same. No I DID NOT mean to call the daughter any names!
Why no RV year, make and floorplan on MY signature as we suggest for others?
I currently DO NOT have one!

Actually, while a sail switch can be a common issue for a Propane furnace. It's likely that you have a heat pump A/C unit. With those, the thermostat can be kind of confusing to turn on "heat" especially from the propane furnace.

So, it's important to learn how to tell your thermostat that you want the furnace to blow heated air from the floor registers and not heat pump air from the ceiling vents. In many cases newer RV HVAC units default to only using the ceiling heat pump and only start the furnace with floor vents when the temps drop below 40 degrees outside.

Looking online, I don't see that your 2019 Minnie Winnie came stock with a Heat Pump A/C unit. However, since it was a used item it's not at all unheard of that a previous owner replaced the non-heat pump unit with a heat pump.

And I'd seriously doubt that they "forgot to attach the floor vents" to the furnace.

Without knowing more about your thermostat it's tough to tell you how to make the furnace turn on anytime you select the heat option.
