Should have brought a Cummins lol. we have had 2 trucks at work with similar problems. turns out that the $8K exhaust system doesnt like off road driving and doing a regen, gets too hot + vibration. the baffles have been coming loose inside. by memory the smoke was white. freightliner payed for the first one and then didnt want to know about the second one.
