I'll see what I can do about the sound. I can tell you this its a little louder in the cab then outside believe that or not. its about a third as loud as a Diesel truck. I'm also averaging around 26 highway and 23 city unless I'm really on it then I'm averaging around 20 to 22 MPG.
Believe me I'm 31 and this is my 12th vehicle. I just got rid of a 2002 Avalanche had a 1998 S10 Blazer before that, and my father has owned trucks all his life has had a new Dodge Ram or Dakota every 3 to 4 years. He never owned a diesel in his life and bought his first Wrangler last year. He love it but after taking a ride and driving mine he loves it and swears if they ever offer the engine package in a Wrangler he will have one.
I don't know what else to tell you guys other than if your thinking of getting another KJ this is going to be the way to go. I absolutely cannot wait to get this thing crawling off road even though its so pretty being a Black Limited, but I knew I wouldn't be able to order exactly what I wanted. So I decided to take one year do the exterior and then do the drivetrain and lift a year later.
I am fast falling in love with this vehicle and I'll probably keep this one unless they offer a 6 cylinder turbo diesel then I'll just transfer all the parts lol. I promise this weekend I'll take some pics of it inside and out and Under the hood without the shroud.
