Took my 5th wheel in for the Dometic refer recall. Recall was done properly. Service writer called and asked if I had a garage to park my trailer in. She said the rubber roof was shot. Accused me of resealing with silicone sealer. The trailer had never been worked on since new (5yrs old at the time) I told her to call the roof mfg as it would still be under warranty, then her story changed! I took my trailer home, scrubbed the roof saw where the factory had used silicone sealer on the sides above the gutters but the proper sealer was used front and rear actually going over the top of the silicone sealer. I removed the silicone and used the proper product to reseal. Touched up a couple other seams and all is well. She said there were black spots where the rubber was worn too thin showing the black backing but after washing they all disappeared, most likely surface mold. If I wasn't savvy her original scare tactic could have had me paying for a new roof!!!! Recall work done properly, Customer Requested 15 point inspection as stated on the repair order was never requested, in fact I would have appreciated them not walking on my roof!!! It's obvious they were trying to sell me a new roof until I stated it is still under warranty then they were not interested in pursuing it!
