One big thing in favor of Jayco is that they use BAL frames and not the usual Lippert frames on 99% of TTs built. Lippert frames aren't known for the best of quality & design and some of them can have significant issues either from new or after several years of many miles of towing.
Jayco has had a decent reputation for some time plus they have a 2 year warranty. They were bought out by Thor Industries and don't know if quality has suffered. TT manufacturers all share the same components - fridges, AC units, doors, toilets, etc., etc. and same luan plywood, vinyl flooring, etc. It's a case of how well all this stuff is put together and how well the manufacturer warranties their units and honors the warranties. I'd also carefully consider dealer "quality" as some are terrible at repairs.
We have a rear kitchen with fridge in the slide and love the arrangement. Way more counter space than most other RVs. What I don't like in that Jayco layout is lack closet for jackets and bulky items and the otherwise small cabinets. With no window in the slide, may seem a bit dark inside. Not sure about the theater seating layout with the removable table like that...
For a TT like that Jayco that is 28' long with 7K lb GVWR, there's a lot of choices out there.
Choose wisely, choose once.
