I have a Mack DM 800 ,tractor version, that I need to increase the wheelbase on. I have a 3-D printed oval tank that will be used with the build.
I have scoured the internet including Big Mack Trucks.com with no luck finding any wheelbase options for the DM 800. I did find one spec sheet for the DM 800 showing multiple wheelbases, but the print was so small that any attempt to enlarge it only blurred it. Mack has a fair amount of wheelbase info. on some of its other models, but for some reason the DM 800 remains elusive.
My question is to those of you who have stretched a frame to accommodate a body (dump,flatbed, wrecker, etc. etc) do you just dry fit the body and stretch it so the the tandems are where they are suppose to be or is there something else involved.
