Mack cab question

[Mustang46555]

That is just the information I needed! After using your dimensions to print some paper templates I totally agree, the R600 is the only choice.
I'll have to move the bed and headboard forward a bit but I had a little to much rear overhang anyway and this should really even things out. I'll be hinging the hood as well for battery access. I currently have the battery mounted Knight hauler style under the frame but I'm going to need that room for the mechanicals as the boom becomes operational.
There's a current picture of 773 in the Show Us your Conventionals section, ought to be an interesting comparison by Indy next year.
Thanks again for the help!
