pclay replied to rsb502's topic in Antique and Classic Mack Trucks General DiscussionDoes anyone have any pictures of a Mack R model 688 in US Army service. The first time I ever seen one was when I was training at Indiantown Gap Pennsylvania around 2008. I saw a few Mack R models sitting in a compound with other military trucks painted green. I didn't have a chance to get a picture of it. I'm trying to get photos because I need reference pics. I'm building a model and I want to make it as accurate as possible. Thanks for your help have a great day.
