She'll be thirstyDid I mention it has a 454![]()











What's funny is my suburban only gets 10-12 normally with, I'm almost always pulling the 20' aluminum trailer though, the back is always loaded down with a floor jack and a 200lb tool box and I like to keep the tank as close to full as possible which is around 40 gallons or 320lbs approx. The 454 will do that pretty much all the time unless you get a big enclosed trailer behind it. I've been watching for a low mileage suburban 2500 with a 454
