yes, the Rockwood documentation that came with my HW277 stated specifically NOT to seal the underside. In the 6 years i had the camper, there was no issue with the floor - it looked just like it did when i got bought the camper new.

Unlike TT, pop-ups have a floor made of OSB or wafer board (not the same as particle board). These plywood replacements are often used in houses. They are water resistant for the purposes of road splash or rain, but will not hold up under long term immersion. If you seal the underside, the board can no longer get rid of moisture trapped against or inside the glued wood - which comes from leaks/spills from above and road splash from below. Hence the warning not to seal the underside of a pop-up/A-frame. The only real way to damage the stuff is water sitting on top or trapped between the trailer frame and the wood (long term contact).
