Beaver Monterey Reservoir
I have a 2006 Beaver Monterey IV 40' coach with CAT 400hp Diesel engine. On the passenger side luggage compartment mid chassis is the Aladdin control module mounted on left. To right sitting horizontally is a large 15-20? Gallon white plastic tank with attached red hose on its right, electrical cord exits below the tank about in the middle towards the left. What is this tank's function/. Hydro-Hot system is to the right with a separate reservoir to the left which seems to be the fresh water for the coach.
