Jayco with a fiberglass roof, which apparently Melbourne has, should be very nice.
Jayco's Brochure Page shows fiberglass roof in their construction details.
Do You and anybody you'll live in it with, like the FLOORPLAN?
For 2014 I see only 26A, 28F, 29D and 29X, not a 29D. Different model year? A "2014 Coach" might be on a 2013 or 2014 CHASSIS and a 2014 CHASSIS might be under a "2015 Coach."
Jayco built some Melbournes on a 4x4 chassis conversion done by Quigley in Pennsylvania. I thought 29x might be one of them but couldn't tell from the quick look I took at the brochure.
