Thanks for all the responses! When you guys talk about rear axles and such, are all the newer ones built with the 4.10 rear ends , or 3.73 (on both the 2500HD AND 3500HDS)? My 2007 classic GMC has the 4.10s, and I wouldn't want to step back into the 3.73.
I think they are both available. Keep in mind that the newer trucks with the 6 speed auto have better low gear launch ratios with 3.73 rear axles than the older 4 speed trucks with 4.10s. Having said that, for landscape work I'd get the 4.10s anyway. Gas mileage will suck either way, might as well get a little more low end performance.
