Pacific Power on the south end of town. They did all of the fluid changes on my DP when I bought it. They also have shops throughout the NW US so any maintenance work they do will be on file. PP is also and Onan and Allison dealer.
If they're full give Trailer Craft a call, they're the local Freight Liner dealer or the local Peterbuilt dealer.
