Now that the heater was in place I could think about a cover. It needs one to protect against the main valve being interfered with. More to the point I’m going to have the ferry tank bladder back there and it will really press on the sides of things so I’m very mindful of that.

Pic 2 shows a foam problem I have. All the stuff I have left is thicker than needed so I have to route it thinner using my thinning box.

Pic 3 and I’ve glassed one side of the cover. Progress.

Trial fit

Foam too thick? Fix it
