How are Mack Pinnacles?

{"text":"I am about to go to work for a flatbed company that uses the new Pinnacles with 70in sleepers. They do have 10 speeds I know. Just wanted to know how they ride, if their engine brakes work worth a flip or not etc. and if they pull a hill decent. The company I work for uses nuetered Prostars with Maxxforce 13's. God, these exhaust brakes are a joke and these things can't pull a hill. I have been meaning to ask a few of the guys I see out there but I am usually securing a load when I see them lol. Any help would be great, thanks! ","pics":"[]","canComment":true}
