Husband and I are newbies. We got our Thor Challenger in late August. Unfortunately, we've only had it out three times. Been in the shop twice- the second time it was in from November 18th until January 4th. Most all was for warranty work. Now we have to take it back because a strip of trim on the outside of the bedroom slide out has fallen off. Looks like all the screws were sheared off. Not to happy right about now.
