Anyone around Pomona? Looking to attempt a 1,600mi road trip in a D100

I’ve posted about this on the fortrucksonly forum but I’ve been unsuccessful... I’ve been looking for a D100 for some time now. Being in NW TN, there aren’t many running options around that are solid. Given my current place in life, I don’t need another long term project. I really want a solid running platform to mess with. With that said, I have found one in Los Angeles, CA. After several weeks messaging and talking to the owner, I have bought my dad and I a couple one way tickets on 4-26!! My plan is to pick up the truck and head to Pomona for the night. I really need to take a day to go over the truck before we head back across the country. Does anyone have any contacts that would allow me to rent a shop space to replace the obvious before we strike out? I’ve called all the parts stores in the area in hopes of someone there knowing of a place but no luck... I would really like to service all the fluids and replace all the rubber lines, belts, hoses... etc. We may still not make it but at least we would have a better chance. If it breaks we will just haul it the rest of the way... Thanks in advance!!
