Underbelly Mod question

[Bearcat55]

My 2012 salem did not come with the enclosed/heated underbelly. I'm thinking about doing it myself but have no idea what it entails. Anyone done this mod or have some instructions on what I need to do?

My fifth wheel's under belly is heated. All I can see is the design was the heat ducts (hose) runs through the under belly. There is a duct that goes to a very large storage compartment with a round outlet. All the vent pipes or anything that passes through the floor has large holes cut to cycle the air. The gray and black tanks have a heat pads on the bottom of each and a heat strip wrapped around each discharge neck.

The heat ducts radiate heat in the under belly from hot air passing through the ducts.

A very simple design. They call this design "HEATED UNDER BELLY"
