Might be a good combo but I'm not a Chevy guy so know nothing about the goodness of the 6.2.
If you want to see the advantage of an equalizing hitch, load 900 lbs on the tail end of the box and go for a drive. It's a pretty good deal to get some of that tongue weight back onto the steer axles.
I have a 3//4 ton and haul a 5000 lb (and growing) trailer. Last year, I bought an Equalizer brand hitch. I have towed the trailer without a WDH and it tracks kike a dream. but I can still feel the difference on the front end.
