Why are the MK48 HEMTT FPU's no longer being made available for sale through GL? I have been told that GL is selling them all back to Oshkosh for overhaul/upgrading to be resold back to the military. Is this true or is there another reason that will be clouded in hearsay like with the HUMMV? Inquiring minds want to know and a green addict would like one. Right now all I have is a brand new in crate cab assy.
