New to forum long time jayco owner upgrading?

[cosmo]

Hello all. Have had a Kiwi 23B since 2003 and have loved it, except for the flat roof. Currently looking to buy a Jay Flight 27RLS. Trying to decide if we want the fiberglass and frameless windows, or the old school aluminum siding. If this forum is anywhere as good as RV.net, I will be very happy. Does anyone know if the fiberglass sided Jay Flight's are a vacuum bonded system with aluminum frame, or just a sheet of fiberglass over the standard wood frame? How about any experiences, good or bad, with the frameless windows? Thanks.
