Furnace blower/fan/registers?

Very new to this so please forgive the simple question. First trip out with a brand new 26RR toy hauler, and I can't figure out the heater/furnace. I turn it on at the thermostat and the furnace definitely kicks on, but I can't find anywhere that it is blowing the hot air. I have the fan setting on the thermostat set to auto (when it is on Lo or Hi it just blows air, not warm air). There doesn't seem to be a fan blowing out the louvres under the stove so I'm now stumped. What am I missing?

The grate under the stove is a return air grill the furnace discharges warm air via hoses and connected to floor or low wall grates. This is assuming the furnace continues to run after start up. The purpose of the lo setting on the a/c fan is only to circulate the space air to keep it even. Eventually it will circulate warmed air from the floor.

Hopefully someone with your camper model will respond.

In the meantime, looking at pics of your trailer on the internet, it seems to be a weird setup. I see louvers under the stove, but no "normal" discharge vents (usually round vents on walls/cabinets or rectangular vents in the floor). I would have expected to see one on the cabinet wall by the street side dinette bench and maybe one in the cabinet in the bathroom. Therefore, I'm ASSUMING that the furnace takes it's cold air in and blows its hot air out through the same set of louvers, which seems dumb, as it short-circuits the air flow. (Not unusual, though, as both my Roo and my Mini-Lite have the cold air return right next to one of the hot air vents.)

I also see that some units have an oven below the stove and some have a drawer. If you have the drawer, you should be able to remove it and get your head in there to see what's going on. If you have the oven, it will be more difficult.

Does the louver seem to be removable? You need to get inside where the furnace is to see what's going on.

Good luck.

Thanks for the help. After figuring out the louvres are the intake I was able to find 2 vents, one in the bedroom and one in the main room, that was pushing hot air out. I had them hidden behind some gear so that's why wasn't getting any heat out. Thanks again.

In my 26RR I rerouted the one in the main room that blows under the seat (or as you said, into your gear). Mine now comes out at the front of the cabinet in the small rectangular area below the 2 drawers. I put a floor grate outlet there with the air blowing slightly towards the rear so it doesn't just blow back to where the air return is. Works much better. Takes a bit of work and a hot air fittings for a dryer unit modified, but is easily doable.
