We had lots of hot water since we bought trailer in March but all of a sudden none. We checked outside shower beginning to think this trailer is not so good! Air didn't work( thanks to forum fixes it is cooling much better) refrigerator and microwave both had to be fixed/ replaced .It could live at the dealership but he is working and we need to stay in it ! Just tried it on gas and it works great in shower,very hot, but not as hot in kitchen. We have a 3690SL. Any ideas?
