Would I see positive numbers with a belly pan on a stock height truck?

Depends on the vehicle. Mine is not the only truck where -- even if it weighed 200# to use galvanized -- the "penalty" would be unnoticeable in any practical sense with but a 3% weight increase. Something that weighs less and is equally durable may be a better choice, but galvanized over some areas may also make sense.

At 1,300 lbs overweight and 65 mph,I'm seeing as much as an extra 23 mpg.
Once up to speed,the weight doesn't appear to impact mpg as much as the drag reduction,so maybe a light gauge steel sheet with stiffeners might be okay.
