When did Thor take over Jayco? Were the earlier Jayco less prone to problems?? Years ago we had a 40 foot Mandalay, I said I would never ever have another Thor product. Sounds like 2017 and earlier should be Thorless in construction, let me know if we should go for the earlier versions Also any underlying problems with Greyhawks? Thank you, the Muffiin Man ( a thor loser ).
