Class C

First RV we bought was a used class C (10 years old), we used it for another 9 years and had NO leaks. 2nd RV was another class C, also bought used (10 years old), and we used that one for 14 years; had 1 or 2 minor leaks during that time that were addressed quickly and resulted in no damage. 3rd RV is a class A, bought used (at 10 years old...hmmm, anyone else seeing a pattern here?). Have had 2 leaks already (1 in front, 1 in back).

My point? ALL RVs (A, B, C, DP, TT, 5er, TC) can and likely will leak at some point in time. Keep up with maintenance and it's really a non-issue.
