Cat3406 Posted April 10, 2017 Share Posted April 10, 2017 (edited) Hello everyone. I'm new to the forum I have been reading through and I'm amazed how much information is been shared here. You guys are great. I have been trying to buy a Mack truck for a while but I didn't have the chance until now. I came across a 2007 Mack Vision conventional sleeper truck with an AC 350 (cxn613) engine setup that really caught my attention until I found out that it has a 7 speed (no splitter, straight 7) transmission. I have never seen this set up before on a road tractor. My concern is whether this truck will be able to pull 80k down the road and especially on hills. Is this engine and 7 speed transmission a good set up? Does it have enough horsepower to pull 80k without issues? Thanks in advance.
