Ryan, If no one in the Denver area writes back, I can go check this thing out on Saturday. I will be driving to Denver on Saturday morning so I'll be in the area.
I have no idea what to look for when checking out a transfer case though. Turn the prop shafts and make sure that everything turns without grinding? Would you need me to pick it up and ship it too, or will that be handled by the seller?
