My 2009 Hawk didn't come with plumbing or wiring diagrams so I thought I'd draw my own. So I took off the front face of the cabinet which exposed the water, electrical and propane routing and connections. Here are the left and right overall views. My Hawk has the hot water and shower option and the three-way refrigerator-freezer, but no furnace. There's a box where the furnace would go. Looks like I'm plumbed and wired for the furnace and other options when I'm ready to add them, though. Nice!

I have more close-up photos that I'd like to post in this topic but I'm just learning how to do it. Does anyone know how to annotate a photo using a Macintosh so I can label pipes and wires and such?
 
On the outside driver's side of the Hawk is a door covering three connections: unpressurized water tank fill, water tank air vent, and pressurized "city water" supply.

This first picture taken under the cabinet shows those three connections on the inside. The unpressurized water tank fill and the water tank air vent go right down to the water tank under the front seat. The city water runs horizontally toward the rear. Behind the city water is the hot water supply from the hot water heater and the copper propane supply for the hot water heater.

Here's the water pump. The inlet is on the right, pulling water right up from the water tank. The pump discharges left to a "T". The water pumped up from the "T" goes to the cold water faucets on the sink and the outside shower. The water pumped down the "T" goes to the water heater inlet. The two valves in this line are 1) to close off the hot water circuit when it might freeze and 2) to drain the system through the clear coiled hose into a bucket.

This next picture is taken under the right side of the sink. The city water supply comes in from the right and joins the cold water from the pump at the "T". The hot water line and the propane line are above and behind.

And a photo of hot and cold lines connected to the sink and the outside shower:

Amazing how much more room there is compared to my Eagle!
I am jealous!
What do you do for heat?
I love my heater and the new ones are even better.

There are also 2 inline check valves in the system. One is at the city water inlet so the pump doesn't pump the water out. The second is at the cold water inlet to the water heater. I think this one keeps the hot water out of the cold water system when the hot water expands.
