It's really no worse than the 454 on gas. The thing I like most about it is the torque. Our driveway is a 19% grade mile and gravel. Going up the driveway I never go over 1500rpm. It's rated to pull 12,000 pounds and I know I have pulled a lot more than that. We pulled a 30+ foot trailer with 2 bobcats with buckets and 2 backhoe attachments as well as a spare track for a John Deere 450 dozer. It did great.Man the 496 I thought I was having gas issues with my 454 lol. I love suburbans they are perfect for this! Doing some more work to ours hopefully get some more trips in this summer.
