It's okay... I can verify one thing... Since the wife is mad at me.. I don't want to be home LOL so went to my buddies and changed the fan clutch.. took her out on the highway..doing 70 and she runs about 185-190.. keep in mind that this is with no trailer... I get off the highway and climb a hill... And she spikes right up over 210... No good... I have to be able to do that with 10,000 pounds of behind me
