Question
gmyeah
I have a 2008 z71 3.73 heavy duty trailering package (is it really heavy duty?). Max trailer weight is 7900# per the 2008 book for 3.73 gears / 5.3L V8, etc.
So, I've been looking at the 2015's since mine is starting to nickle/dime me to death with throwing codes. They only offer a 5.3L z71 with 3.08 or 3.42 gears. Interestingly enough, the 3.42 has a maximum trailering weight of 9200#...more than my current 2008. So I guess GM upped the GCWR somehow....good for me. Did they up the payload too? If I go with the 3.73 gears it throws me to a max trailering package which boosts me up to 11,000# max trailer weight for a 5.3L V8. My only gripe with my current vehicle is I could use a little more towing capacity, but definitely some more payload. I looked on the GM site and they mention the max trailering pkg comes with bigger rear axle, higher rgawr, heavier duty leaf springs.....so i assume more payload? I couldnt find any payload #'s with this setup. how much more payload compared to the non-max trailering package.
If i were to go this route with the max trailering package, would i get about the same gas mileage as my current 3.73 2008 z71 5.3L. Seems like it would be close. I just don't want to say later....I might as well have gotten a 3/4 ton. I do a fair bit of firewood/renovation/etc.....so I sometimes only use the bed and it really gets loaded......but even squats pretty easily even with a light load. Thoughts?
