Who ever told you towing with a body lift effects the ability to tow, should be stabbed in the neck with a knife. That would ONLY apply if you are dumb enough to pull a trailer with a bumper hitch to begin with.
You're not gonna need much "drop" on your hitch, probably 2-3" at max I'd guess.
If you stiffen the torsion bars, the ride quality is going to decrease. Not much, but it will. For the money you put into the truck for 33's and a BL, it's worth the money if that's the desired height you're after.
