I agree that a clutch fan is more reliable for cooling, especially when towing.

It can be done with a turbo. Most of the kits I've seen need a set of electric fans. But with a little creative work, you can re-route the cold side to work with a mechanical clutch fan.

 

If youre towing heavy that makes sense, Ive only towed with my truck once with the setup on the highway and it was in the 50s so cooling wasnt an issue

I would assume youd have more room than me to play with cause I kept my battery in the front corner because im planning on getting a second because I have a plow. Id think if its moved to the passenger side corner thatd free up some room?
