I went from a 97 Z71 extra cab to a 2007 DMAX/Allison crew cab 4x4 and love it. Like others have said I plan on having this truck for a long time and you cant beat the power of a turbo diesel. The gas truck will get you there. I put over 200,000 on my Z71 towing all over the place. My stock diesel gets better mileage than my gas truck too, towing or not. An upgrade to a 3/4 ton is great as well. They feel so much more solid than my previous 1/2 ton. They go through tires faster though...a lot more weight. I was lucky to find an 07 with 9500 miles on it..I didnt leave the lot without it!
Here she is!
