I just recently traded my DP in for a Class B+. There were a lot of reasons for doing this, but one reason was the cost of maintenance and finding places to do it. I live in Reno and basically the only place I would trust is the local Freightliner dealer. There are a few places around town that will do the oil changes, but not much else. Before I traded it in I was trying to find a place to replace the serpentine belt but couldn’t find anybody to do it. So I’m stuck with Freightliner which leaves a couple of problems. One being they are expensive as heck. But mostly it’s because Reno is a huge trucking hub and the only place big rigs can get repairs in a long stretch of I-80. So they are swamped with work and they are going to give their commercial customers priority. I’ve tried to make appointments there and they tell me I need to leave it for a week and they’ll work it in.
