Just curious if most of the heat in a class a is supposed to come out of underneath the bench? Seems in the bench is quite warm and there is a vent there leading to under the table, as well as a vent in the bedroom and up front but those two don't put out as much heat. Any suggestions?

Distance from the furnace is the biggest, thing to consider in heat distribution, the longer the hot air is in the duct work the more heat loss, in your case the furnace is probably under the bench.
Every floor plan will be different.

If you have an adjustable vent, partially close the one under the bench. That will force more out the other vents. The vent nearest the furnace will still be warmer, but with less flow from that vent, the others will better heat the other areas. Play with the amount of closure until you're happy with the heat distribution.

Good Luck!

Each of the vents are plumbed to the furnace via a flexible ducting. Depending on where your furnace is and how the duct is run could influence the amount of air coming out. Have you looked under the bench to see if the ducting is fastened to the vent or just blowing into the bench area causing a loss of efficiency.

Implicit in your question was that all Class A's deliver heat in the same manner, but nothing could be further from the truth. Each manufacturer and floor pan will be different, and some don't even have heat under the "bench" (dining area seat?). So for starters we need to know the year/make/model & floor plan of your RV.

As others have said, there are a variety of reasons related to ducting that causes uneven heat distribution. I'll add another: a duct can be collapsed or kinked enough to severely reduce flow, forcing the heat to travel through less obstructed paths. I had a brand new 2002 coach that had 3 of 4 major ducts crimped to some degree, right from the factory. A factory service tech removed several feet of excess tubing and straightened out the tubes so that heating became much more even.

I have a 2000 Monaco monarch, it looks like its flexible tubing under the dining bench, not affixed to anything.

Have you located a vent the hose should fit yet?

Dustily · 01-03-2015, 08:29 PM

Looks like it all fits, we are going to have to go through it and see if the hose has any leaks or try closing off the one vent as suggested. I thank all of you for all the help!!! This is all new to us!!

Our bathroom heater vent was closest to the furnace in our last MH, so it would get really warm. Looked to see if there were any kinks in any other hoses. They're weren't. So, I took a piece of heavy duty aluminum foils and experimented by blocking the br vent partially off to force heat elsewhere. Took about 50 %. Worked great.
