Depends on what you consider "light/medium towing". To me, "light" towing is my 5x10 trailer with my 1,200lb z-turn or my atv hooked behind my truck. Medium towing would be one of my gravity wagons or a smaller double axle spray tank loaded. My Toyota Tacoma with the 4.0 v6 does everything around my farm I need to do and then some. does the same amount of work my previous Z71's did and this doesn't stay in the shop like they did. when you want to drive around, mine gets a consistent 20 mpg. I'm not a fan of AFM(active fuel management) like you'll find on RAM and GM trucks, so if a v8 is what you want, my pick would be an F-150 with the 5.0 or a 5.7 Tundra. If we're talking Diesel, make mine a Cummins, please.
