2500 won't be bad depending on exhaust. As with any build in a enclosed vehicle like a car, suburban or blazer in your case. Exhaust choices will be a bigger make it or break it item then rpm.

I was towing a 5000 pound trailer yesterday up the grape vine doing 3500 rpm. Engine ran smooth, and no excessive noise. I couldn't hear it over the talk radio program I was listening too either. I have the 4.3 LV3.

Personally I like 4.11's, but alot of that depends on available traction.

In my opinion any gear from 3.55's to 4.11's will be a great all around gear.
