I am used to driving tractor trailers with an 80,000lb max; however now, I am trying to help family with a couple of dump trucks. We have a 1996 Mack model CL713 and a 1997 Mack model RD690S. On the side of the CL713 it says an ID number, then GW 57,500 then NW 32,040. On the RD690S it only says GVW 70,000. They both have a 'trailing' or liftable axle, but the owner wants them removed to max out payload weight and in GA where we will be traveling I don't believe they are necessary. What I am trying to find out is what is the GVWR for these trucks to be legal? I am just not sure how to understand the numbers on the sides...70K lbs seems like a lot of weight for such a short truck and the aluminum box truck has the GW and NW and I'm not even sure I know what that means. Please help...thanks in advance!
