Jayco fith wheels

We ordered a 09 Jayco Eagle 313RKS and since it has had many + and -'s. We have gone through 3 slide motors for the big slide. Jayco did help us even when the warranty was up 50-50 deal. Ours is a rear kitchen and we are on our 3rd Norcold fridge door and the last time there was nothing stored on the door shelves. We travel 6-8 months a year all seasons and polar package is lip service, when the furnace is on it's warm when it shuts down you're chilly. It's probably a decent vacation and camping rig but long term travel no way.
