My 1987 M985 went to Oshkosh for a "0 Reset/Recap" program in 2001 at their plant in Oshkosh, Wi. At that time it was stripped to the bare frame and rebuilt as a new truck warranted by Oshkosh for 12 months or 12000 miles. Then in 2009 it went through an RSMS O/H in Saginaw, Tx. which would be servicing, paint, tires, brakes and any other required repairs. I figure that between original cost and both rebuild costs there is somewhere around $750,000 in tax dollars in this particular truck. I can't say if there are any O/H sites other than Oshkosh at this time, others may know. I am sure there are several repair facilities around the country for the HEMTTs and do know there is a facility in Ogden, Ut. that services and repairs a wide variety of military vehicles including the HEMTT series of trucks. There is also an acceptance facility in Ogden that usually has several new M1120A4s and M984A4s lined up for inspection and dispersal.
