since this is a Forest River Owner's forum and not a Jayco owner's forum, not sure how much input you'll get about the Jayco.
but Jayco makes a good product but so does Forest River brands.
the only solution is for you to look in and around each one. open all the doors, peek around, test everything.
no substitute for you doing it personally. everyone's opinion of what is quality and fit/finish is different. it's all very subjective.
both brands have fans and haters and both brands make jewels and lemons.
