torquey cam for 6.2?

what's up everyone well i just sold my sss and am buying a 2010 silverado crew cab 4x4 with the 6.2 and i was wondering what cam ya'll would recommend for it to get some better low end and mid range with out losing too much mpg i know its not going to be that great anyway but don't want to hurt it much. Also will tow with it pretty often so gunna use the factory converter.

any info will help.

I get 20 hwy in my 6.2. But like 12 city.

thanks thats not too bad what mods have u done to the truck?

Tune, headers, muffler. I'll be camming mine soon too, but I plan on something a LOT larger.
