Furnace and generator in one bay

[TomC]

While propane water heaters are used widely, I didn't use one since they again need to be cut into the side of the bus for ventilation.  They are now made in sizes up to 16 gallons.  Also, when they kick on, the burner is on the noisy side-especially on a quiet nite.  Personally use two 10gal electric water heaters straight from Home Depot that have been zero maintenance (except to drain periodically) in 15 years.  Good Luck, TomC
