Basement Vent
How much heated air comes through the furnace basement vent when working properly?? I can't feel anything coming out the vent. This is one of numerous issues being addressed by the dealer service center (unit is still under warranty).

I think you will find that the "vent" you mention is for air to pass through it naturally and nothing is attached to either side.

On our rig, as stated by David, that's a air transfer vent not a heating vent. Since I did want a vent down there I drilled three holes in the heating duct that runs across the basement ceiling, spaced evenly across the basement.

:-). No wonder the service center said it was working as designed. How does the furnace warm the tanks and lines? Radiant?

There is a separate 1.5" duct simply laying hap hazard down behind the back wall of your storage area pointing into the belly. Like said a few times earlier ... the vent in the back wall itself is pretty ornamental. Since I seldom winter camp, I covered it as in summer it lets hot air back into the living area especially on a windy day with a storage door open.

Heated tanks really is a marketing point and has nothing to do with reality. That small furnace duct can't do much for the shower and black tanks, don't expect anything to the galley grey, and nothing to the rear of the rv for fresh water tank. More heat from the living areas gets into the belly through the passive vents to condition the tanks, etc. John

Interesting discussion. If the tank heating is really marginal, what have folks done to help warm the tank area? I have thought about a small heater or light bulbs? We had a SOB that claimed to have heating ducts in the tank area. We have not winter camped but the chance is coming.

Depends on how cold it gets and stays whether the Monty system works or not. Blocking wind from under the rig and small heaters or light bulbs will then work if it gets really cold and stays there.

The new units have heating pads on the tanks to keep them warmer while the temps outside drop below freezing. At least that is what we were told at the Fall Rally anyway!

The system seems to work well, thousands of folks live and travel in freezing weather and the tanks don't freeze. I am a Hvac guy and find no need to modify anything concerning the 'belly heat' that might change if I were in sub zero weather for a winter, don't know.
The return air is what heats the basement area, on that subject I have always suggested a filter in the return grill under the steps ( on my older 3400 rl)

just my opinion, if you are 'camping' in an area where you have to worry about your tanks freezing you should be i a hotel. it would take alot of cold weather to damage and freeze your tanks.
as for your pipes, you will be okay if you have your heat on in the trailer, outside is another matter. but, just look at what your neigbhor is doing to keep those hoses open in cold weather.
