Liquid Holding Tanks protected against freezing on our 89 GV?

August 20, 2011, 01:49:43 am

I was wondering if the older coaches came with any cold weather protection for the holding tanks? My old class C furnace would blow hot air into the tank compartments. Not so on GV? Any way I could provide some heat?

Nitehawk, My 280 has ducts into both the water and storage bays.  Look for a small ( about 2 inch ) flex hose behind the water panel.  There is also a opening between bays that allows heat to pass.  In addition the Inverter charger makes a bunch of heat that will heat a bay.

Thanks Gary. I'll crawl under the coach and look after the rain puddles dry up.

No cold weather protection. The tanks and drain piping are almost totally exposed. The tanks sit on support "paneling" and the valves are the only thing in a side compartment plus the converter and drain hoses.

Nitehawk, OK I failed to see that you had and ORED, different animal from the later 280's.

My '92 U-280 also has ducted hot air into utility (water tanks) bay from the rear furnace only, so if you aren't staying in the coach when it's cold out, at least make sure that the rear furnace is at a minimum temperature.

My 89 U280 has a furnace vent into the basement. It's on the basement ceiling pasenger side and is fed by the rear furnace.
