Congratulation on the new 5er and truck. I think you will really enjoy what you have purchased.
Now you need to join a another forum. I know Rusty and I are both members of Turbo Diesel Register there maybe others on this site also. On this site you can purchase a trial membership and decide if you like it or not. TDR offers some advantages that other forum sites do not offer. Such as a members "Travel Companion" where members have agreed to offer help to other members if they break down when traveling. Another feature is TDR publish a quarterly magazine that is geared for the Cummins diesel owners.
