A FR fan, but in this case I would go with the Jayco for a few reasons. Unless you HAVE to have the 3 bunks, I think the double bunks would be much more comfortable. Never have been a fan of triple bunks....too tight, to narrow, claustrophobic. The Jayco offers better kitchen countertop space, while the FR has virtually none. General layout is pretty similar, but these differences would make me go with the Jayco.
While we very rarely buy the extended warranty, we did on our Rockwood and, yes, it is transferrable to a new owner. There is a $50 charge to make the change, but I would consider it well worth it.
Good luck on the decision and happy camping!
