Does anyone recall whether or not there was ever an issue with Hart's Encore roofs?  Is the Encore roof the same as the "honeycomb" roof they are using now?  I don't know if they are the same or what year they switched if they are not the same.  I ran across a 1997 Hart trailer which is why I'm asking the question.

I found this... Doesn't look like the "Honeycomb Core" roof is the same structure as the "Encore" roof.

  Quote... "All HART roofs are 5/8” thick fiberglass reinforced structural panels with a R3 thermal value for the ultimate in temperature, quietness, and strength. The HART roof is a structural grade polypropylene honeycomb core material with a 1/16” layer of fiberglass resin and woven matting top and bottom, finished on the top exposed surface with a gel coat. The gel coat finish provides a high gloss panel, with long-term protection built in. The “HART Honeycomb Core” roof is 55% lighter in weight than the previously used “Encore” roof. Additionally, it will not dent when subjected to hail, tree limbs, or the occasional rank horse that throws its head up into the ceiling. We use it at HART because it is simply the very best material available for a horse trailer roof. Besides we think you and your prized livestock deserve it."

Our little trailer is a 1994 or 1995 Hart 2H BP, not sure of the model but it's never had any roof issues and I drive it all over the place.
