I still have two questions.
1. Everybody seems to agree that the clunking when shifting is bad. As I new driver I have heard it but unclear as to what causes it. Can somebody tell me how to avoid clunking?
2. Will towing a trailer make this problem worse? Eventually I want to get a pop up trailer (no lectures about how after market trailers voids the warranty), and want to know if that is a bad idea with a F3-T.

Thanks.
