Buying a two or three year old Trailmanor

I have a few questions for those who have purchased a used Trailmanor.
1)What types of things had to be fixed?
2)Was there much expense?
3)Did you do the work yourself? Was it difficult getting the correct information to do the repair right? How long did it take to get parts?
4)If a dealer did the repairs, how satisfied were you with the quality and price of the repairs?
5)I have read on the Forum that screws and fasteners often work their way loose. Is it just a matter of replacing the fastener or do you have to replace it with the next size up.
