Well, my 6 year old unit didn't look like the underliner was ever removed, but maybe they were experts at it. Also that magical silver blanket was completely intact until I cut it to get at the water tank mounts. And I would suggest that if actual insulation had been installed (and removed as you suggest), that would have interfered with the airflow from the heating vents under the floor that are supposed to keep the water lines from freezing. It would make no sense to put in air vents and then block with the air flow with insulation. But it also made no sense to put in a 40 gallon water tank and not support it properly, so maybe they did.
I seem to have really upset you because I expected a properly designed and constructed trailer, even as the second owner, and there are a few design flaws, that were later corrected in following years. You seem upset that I voiced my complaint to Grand Design, who has shown goodwill and agreed to replace the damaged parts, and I have tried to alert other owners of the possible danger in their own RV. I expected Grand Design to stand behind their engineering, even six years later, and they did. Why does that upset you?
