    That’s what I figured. Thanks

    I honestly dont know, 2.7-3k? I guess, but I set the cruse at 80 mph often... I'll have to check the RPMS... never really worried about it because there is nothing I can really do to change it without an LS or 40s

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
