@Birken_Vogt nailed it. The NO DEF SCR type of emissions system have 4,000-5,000hr life before R&R on the heavy equipment side. On the truck side that seems to be in the 300,000-500,000 mile range on OTR type trucks. Fleet trucks that get turned in on the 2nd market are typically 30-40 months old and have right at that same mileage range.
CARB has really screwed up the trucking industry in California and they don’t care about it. On fire engines, the emissions systems have had to have all “limp” safety feature removed due to life safety. I know some depts have started a 24mo R&R of the emissions systems for this very reason. On the equipment side of things, the engines will “Limp” when they approach 90% capacity and require a REGEN BURN to self clean. There really is no good answer. If you have the $150k budget, you can get a 2012/newer Type 2 and possible a Type 1. Unless you are using the Type 1 for the farm, it doesn’t pencil with the difference in pay for the Type 1 compared to the Type 2 IMHO.
