Thanks for letting me join. I am not an OTR but I do drive a 2012 Freightliner m2 6 wheeler to deliver and set up concrete burial vaults (Wilbert concrete vaults that is) I have put a little over 100000 miles on it and drove a 04 Freightliner and put 280000 on it also. Thanks again for accepting me. As I say I will be the last to let you down. Vaultman.
