But even newer 1/2T's have clutch fans. My neighbor has a late model F150 with HD towing pkg and it has a large clutch fan - because that's what it needs to keep temps down.
Also, you do not want to add an electric fan to a system that already has a clutch unit. The electric fan will block airflow and cause performance issues. Besides, pusher fans don't work nearly as well as pullers.
What year is the F150? Every model I've seen (at least the EB engine) uses twin e-fans. Fuzzy photo, but you can barely make out the fans behind the rad:
Not saying that's the solution to the OP's problem, just that there shouldn't be a perceivable power loss on a modern 1/2 ton. 1 - 2 mph loss, maybe, not 10 mph.
My 2014 Ram hemi uses a shroudless e-fan in front of a mechanical fan. I've since deleted both and installed a brushless e-fan from a Pentastar. Not overheated once towing 8500 lbs, though our temp don't get that high.
The modern 1/2 ton Ram has a higher GVW with only a brushless e-fan (higher wattage than mine). And we know how strict OEM cooling certification is!
