Very happy with my boyd's tank, which I only swapped to during the LS conversion. The tank in the cab didnt bother me other than the occasional smell. It also kept me from smoking in the truck
which I'm happy about now, having quit about a year ago.
Having the added weight over the rear axle seems to help smooth out the ride and it likely hooks up better (if I was still trying to go fast in it).
Not having a spare tire sucks, though. It hasnt burned me yet but I know one day it will
