Not any more. The Ford 6R140 is also used in class 6-8 F670/F750 trucks. Most people think that just because the F750 has a 7 in it then it is a class 7 only. However, some variants of the F750 have GVWR's above 33,001 lbs which makes them a class 8 heavy duty truck.
Professional truckers would laugh at you for calling an F750 a Class 8, even if it does require that level of a CDL !
As noted, ANY rig with a gvwr over 33,000 lbs is a class 8! That can be a single 20K rear axel, and a 20K front, total 40K. Tandem rears are 34,000 plus front usually a minimum of 10, usually 14-20K capacity. Assuming they have the tire capacity in width. With typically 10-12" width tires, that is only 12-15,000 lbs, plus rear capacity.
I've seen single axel tractors Like the F750 pulling double and even triple trailers, pushing those rigs to 80K+ lbs. I have to admit, the F750 was not really designed for that weight per say.
THere is NO difference in CDL for a class 7 and 8 rig. Same test etc. Not sure how or why a professional trucker would laugh at one saying an F750 wasn't a class 8 at times. On the bottom end of the GVW scale........
