Any truck loaded the exhaust brake aint worth a toss.
Engine brake better, intarder the best.Depends, on at a previous job we had ‘stronger’ ones on our Volvo’s so if you selected the highest setting before the hill it would keep you in a silly low gear max revs whilst descending. They were good enough on the 750’s that were plated for 120 tons. It saved the company money on brake pads.
If its got settings its most likely an intarder especially if heavy haul.
