Serviced both M923s: oil & filter change, replaced wiper blades, greased zerks front to rear
Then outfitted both trucks with: 40ton bottle jacks, wheel chocks, slave cable jumpers, slave cable impact w/ lug nut socket, spare tire chain hoists, flares, reflective hazard triangles, and fire extinguishers. Neither of the trucks had these accessory items when purchased. Learned early in life (Boy Scouts) to Be Prepared, and I felt the need to stock both trucks for emergency situations. I have a long want list, but at least I'm making a start.
