2005 Keystone Zeppelin Z241 brought in for scheduled appointment to repair minor water leak at 6-way fresh water connector in bathroom. Leak discovered first day I had the TT, took 3 weeks to get an appointment to take it back in. Connector is located UNDER the shower pan, cannot be reached through trap door at front of shower pan. I was told repair would require removing shower enclosure, fixtures, drain, and shower pan - which was why they could not perform the repair the first time I took it back to the Service Dept. Instead of performing the above procedure, the technician CUT A VERY LARGE JAGGED HOLE IN THE LAMINATE BATHROOM WALL, SO HE COULD REACH DOWN AND TIGHTEN THE 6-WAY CONNECTOR! The hole is located on the wall under the shower pan. No attempt was made to then repair or seal the wall. The hole measures approx 5" wide and at least 5" tall. It appears he partially removed or pulled back the shower enclosure, reached in and cut the hole, so he could reach his hand down the wall and tighten the loose water line! When I dropped off the TT, I also asked that they make a few minor repairs, such as replacing the waste water drain pipe and cap, secure the sensor wires and hose under the unit, do some caulking. Unit dropped off Tuesday 9am, promised Friday close of business. I called at 9am Friday, told to call back at 2pm. Called back at 2pm, was told only the leak was repaired because "a lot of our mechanics took off for the Laughlin Nevada motorcycle run". I was also told that I could do some of the requested repairs myself, such as the caulking and securing the sensor wires! I WILL NEVER, EVER USE THEIR SERVICE DEPARTMENT AGAIN! And yes, I am contacting Keystone and sending them photos of the hole in my wall. Their service departments get poor reviews from customers, against my gut instinct I took my TT to them only because they are the only authorized service dept for warranty repairs on the Keystone Zeppelin. I gave them the benefit of the doubt, and they totally screwed up. HORRIBLE.
