I'm thinking about adding an Isuzu NPR Dump truck to my fleet. I'm a little gun shy about pulling the trigger. I bought an Isuzu Vanscaper last year and I doubled my customer base this year so the truck pays for itself. I'm thinking the same will happen when I buy the dump truck. I'm looking at a 2007 similar to the trucks they run with the 1-800-GOT JUNK body on it. The dump body is 10ft x 96W x 60H. Is this box too small? Anybody run one of these in a dump? The GVW is 14,500, I don't want to out grow the truck before I even get it.....any feedback wil be appreciated.
