Several things you need to consider.
-do you have an RV repair shop that can do warranty work for any brand?
- do you plan to use TC only in your area? Most of owners do repairs 2000 or more miles from home
-educate yourself when picking up new camper and don't hesitate to walk away if it does not meet your expectation. I know it is not easy decision, but once you accept inferior craftsmanship, you might never get it back on right track.
BTW TC don't require oil changes, so you don't have scheduled service on them.
