Sorry to hear of your problems.
We also had a shower leak but it was fixed by the dealer and we haven't had any problems since. The dinette table wobble was the only other thing that we have had fixed.
Overall it has been a great rig. We taken about a dozen trips with it in the last year. Most have been within 100 miles but we did put about 1,500 miles on it during a three week trip in May.
FYI...there is a long ongoing thread in the Flagstaff forum for owners of our trailer (the Flaggstaff 27RLWS is identical to the Rockwood 2703WS) so you can find some good information there.
