If you have delamination you have leaks. Period. I know first hand. I too had a $16,000 dollar brand new Fleetwood Terry TT back in 2001. It had soft water logged floors and major delamnation within 3 years. I did what I could to find the leaks and patch them up. I also had to replace 1/2 of the floor of that 30 foot trailer. (The other 1/2 rotted out within the next 2 years) by year 6, all of the cupboards had black mold and it was almost unlivable with the smell. Needless to say, I sold it by year 6 for $500 with FULL disclosure of rotted floor, mold and delamination. Very expensive lesson learned. I did my homework second time around. I actually bought a 40 year old camper that has a FULL fiberglass roof and nose. Paid 1000 cash and renovated it. Sorry about your lemon, but most RVs are inferior nowadays.
