They took a ride out in it with me, and did hear the noise I was referring to. It very well could be normal since I have heard it since I bought it new. They told me not to worry that it was completely normal. Also, I noticed that today after my gas tank got to the 3/4 tank full mark, the noise I was describing in a previous post that I thought was pinging completely went away again. Seems to only do it until the first 1/4 tank of gas is used up. This is the second tank in a row that it has done this then quit like that. Then it quits. I also discovered that the 'pinging/tapping' noise I was hearing that sounded like my side windows flapping on the metal support bow was indeed just that. The wind was a bit stronger today than it has been the last couple of days, and it was flapping faintly and heavily -- each time when the wind was blowing. One down, a couple more to go. : D |

They took a ride out in it with me, and did hear the noise I was referring to. It very well could be normal since I have heard it since I bought it new. They told me not to worry that it was completely normal. Also, I noticed that today after my gas tank got to the 3/4 tank full mark, the noise I was describing in a previous post that I thought was pinging completely went away again. Seems to only do it until the first 1/4 tank of gas is used up. This is the second tank in a row that it has done this then quit like that. Then it quits. I also discovered that the 'pinging/tapping' noise I was hearing that sounded like my side windows flapping on the metal support bow was indeed just that. The wind was a bit stronger today than it has been the last couple of days, and it was flapping faintly and heavily -- each time when the wind was blowing. One down, a couple more to go. : D |

They took a ride out in it with me, and did hear the noise I was referring to. It very well could be normal since I have heard it since I bought it new. They told me not to worry that it was completely normal.
