Okay, so I decided not to go with the 1978 Chinook. Too high of price for the work that would be needed. I am now looking at a 1976 Scat. It has dual tires in the rear with 5 lugs. I have been reading about them on the discussion board. I do not know yet if the rims are welded together. The seller said the Scat was not included in the recall, but I saw someone mention the recall was for ALL RVs. The seller is not the original owner. Can someone tell me if they know where I can go to verify whether or not I would need to swap out the axel? Could I simply change it to single wheels? If so, would the size of the tires be the same as those on the front or should they be wider? Any advice is greatly appreciated.
