You wanna share a picture of the twin 16" fans?Zirgo makes a single 16" at 3630cfm
A pair of those would likely handle any heavy towing a person would do short of a hot shot driver pulling max gvwr every day.
My twin 16" fans pull about 5000 cfm combined and have never let me down towing up around 6000 lbs.
Well just ask Shawn and Tyler. Shawn towed Tyler's truck to the DP challange a few years back with them on with no issues what so ever towing at least 12K. Also neither of them had it wired to the AC and i dont either.could they handle the AC at full blast in 115-120* with much hotter road temps running across the CA or AZ desert? im gonna assume it couldnt handle those conditions with a 5-6k boat in tow?
