You mention you used, "Closed Cell Spray foam" to insulate the flooring of your Laredo. You didn't mention the brand you used. Is this something you applied or had a contractor apply?
Is this a waterproof foam? If not will water splashing up there deteriorate the foam?
In your photos it looks liked the existing insulation had been wet?
Happy trails,
Yes the existing 4'x4'x3" batt that was under the lack tank was soaked! Bayseal is the brand made by Bayer Environmental. I am a contractor but you could do it yourself with a DIY kit from HD or Lowes. My 36'er used about 600bf to do in between the frame rails. The DIY kits usually have 600bf. Yes CCSF is impermeable...meaning water can't penetrate it. I did re-install the coroplast and ran a bead of sealant down the frame to try and minimize water intrusion.
At 30deg outside temps...my furnace runs half as long and there is no more "hot line" on the floor. At it heats up, rather than the heat rising too fast due to it having a draft through the floor to pull in the cold, it is a much nicer even heat. In the 80-90deg range the 13.5k ac purs along and cools things off in no time. Just the opposite of the heat cycle, cold air settles and drags hot air in with it. Now the CCSF stops it from settling out the floor.
Sorry for Hijacking! Sounds like you have a duct that isn't connected in the roof! If you can find someone with an infrared camera. You should be able to walk the roof with the ac on and find the "colder" spot.
