Great, truck! Mechanically sound and maintained. The sought after LBZ Duramax, last diesel before the DEF and extra emission restrictions. Regular lube, oil, and filter changes. Transmission, transfer case, and differentials last flushed/serviced at 215,00 miles. Only non-OEM "upgrade" is FASS fuel system added in Oct'22. Repairs/replaced: glow plugs (R side) Oct'22; fuel injectors ($6,000) Oct'23 at 237,000 miles; hydraulic brake booster Sep'23; new Interstate batteries Mar'24; glow plugs (L side) Jan'25; starter Mar'25; alternator Oct'25. Runs great. Work it, farm it, or restore to pretty.
