MojaveJoe, general maintance is nothing on your truck. And if you ever did a valve ajustment on an old Chevy v8, it's that easy on a cummins. It's been a decade since I moved from that area, but the hardest thing to do was get rid of the oils, filters and such. You can go to the fairgrounds and the fire department has a place you can drop all that stuff off for free, (or they did when I lived there). Just the major work was the problem in that area.
I use to live in the Eagle Ranch track, and I've got family and friends still there, and from what I have seen the place has blown up in size and population. Got an email out to a friend that owns a Ford diesel to see if a certain shop is still open. Been so long, I want to make sure the shop didn't close. But Apple Valley is a bit closer than Palmdale. (nothing wrong with the Palmdale area, just the distanc eto get there). You should check the Hesperia area out, they had one heck of a lot of mechanics there, many for diesel.
