Warranty Issues and denials

I had problem with our new Laredo. Winterization valve was not plumbed correctly. I was going to just fix it myself but on the next trip out I noticed that 2 of the 4 brakes were cold to the touch. So I decided to take back to dealer for repairs just I case brake prob needed parts and was not just loose connections. I called and scheduled an appointment for Jan 2. I had the camper at our hunting ground for the season so I scheduled a trip to get it to them. I called them after not hearing anything for 2 days. They told me they had not gotten to it yet because they were busy getting ready for the RV show the next weekend. Obviously new sales are more important than customer service. When I went to pick camper up they just handed me keys and said it is outback. I went to raise landing gear and battery was dead. I thought this was weird but just wanted to get it home. When I got home I realized after truck had charged battery that they left water pump on after testing plumbing repair. I called to ask them about how long the pump could run dry with out causing damage and to express my concerns about what happened. All I got was him saying well that is the last step to turn off pump they would not have left that on. I expressed my concerns about coverage of damages later down road. All they said was sorry. I can't wait till warrenty is over I will be hesitant to take back for anything in future.
