I mark this as "modified" only because I added the dump box from an Autocar kit. Everything else is box-stock. This is an original issue kit over 40 years old.

Built box-stock but I added the dump box, this is an original issue kit, 40+ years old from the Gary Tanck collection.

This is my newest Mack DM600 I brought from Hobbylinc. Still being built. I am hooking this one to the 3-axle gravel trailer also available thru this wonderful on-line store!

This is a start of a "highly modified" version of the kit. This is the second kit I bought thru Hobblylinc.com I am attempting to create a 'long nose' and I am adding a cement mixer drum from an old DM800 kit.

Here I am building both Macks side by side; but I am switching the chassis of the two. The models are both presently available from Hobbylinc.

This picture shows the DM600 on the left; This should help show you the difference between it and the centered cab of the R-serious of the AMT kit (on right).

I'm building this one Yellow & Green, and I will be adding the dump box (option) from the 3-axle gravel trailer kit. The trailer is presently available through Hobbylinc.

I'm making this one into a Cement Mixer. I used two DM600 frames and extra axles and a "Rex" mixer kit from an old Ertl/MPC.

This shows a little bit how I created the "long nose" and open side hood. By Gary Tanck

This is another customized version of the DM600 kit. I centered the cab and made custom fenders & grill and also the headache rack.

Here i am showing how it would look with the gravel trailer kit that Hobbylinc currently has available. The trailer kit has a customization option & comes with the cab-cover/front end. By GT Classic Plastic

Being built with the frame from an AMT Mack kit (cause it's longer) and adding the "dump box" option from the mpc gravel trailer. Also used chrome rims. By: GT

This one was built with an R-series frame/chassis (because its slightly longer) and wheels from a Kenworth and with a dump body (cut down from a dump trailer). Go Pack Go!
