First Job Issues

7 gears to get to 25 mph? Dang you gotta wind those RPMs up a little higher before you shift I think.

 

That kind of load is tippy. Easy on the corners.

 

Does this help? I've had trouble finding what the gross weight is. It seems to be the vehicle weight + 30,000 lbs. Those slabs vary in size, but weigh around 1000-1200 apiece, I am new to this industry - I would have thought that if the max load is 30k normally people would haul slightly less than that, especially if going through mountains - or is it normal to carry a max load?

 

Typically in the US tandem drive axles are legal to 34,000 lbs and a steer axle is good to 12,000 lbs. So I could see your payload being 30,000 lbs if your truck is setup that way.

If the spec sheet you posted is for the truck you drive then you definitely shouldn't need to be shifting 7 gears to get to 25 mph.
