Hi; I have not posted before on this site but have visited it frequently; Reason for posting, I've had it with 8.5 mpg while towing. I currently have '03' GMC slt. 8.1 /Allison, that is loaded and we (DW & I) both really like this truck. Wife has back problems and the heated seats let us drive 8-10 hrs without difficulty. We tow a mid profile 5er and last year towed for 13,000 miles out of a total mileage of 26,000. I'm currently seeking a match to our present truck with Lb7. My previous reluctance to go this way has been the injector problems i've read about on this and other forums. However, enough is enough already so as soon as we can-- New truck. I'm not new to diesels however as we previousl owned two pusher class A's, one with 225 cummins and the other 385 c-10 cat. Glad to be included in this very informative forum.

Welcome!

Had an 8.1 '02 GMC HD. Good truck, good power. The 496 makes really good torque for a gasser.

I have two of the Merc 425HP 496's in my boat.

Had it with gas economy and the cost?

well let me tell you something.... :eek:


I've towed the same boat with the 8.1 and my LLY DMax. You'll never go back bud!

Good to have you in the brother (and sister)hood. When you get a chance, create a sig showing your truck options and modifications so users can help you easier. And we will all want to see your ride so feel free to create your "Garage".
