i have the flexalite fans and a 160 t stat. it was good for awhile but this past few trips coming home from the lake the temps have been jumping like crazy up grades (last trip 250 up one particular grade). before this it would hang around 210 or so and in colder climate around 190-200. both fans are on high the whole time. bad t-stat? go back to stock? change flexalite efans over to factory efans and run through tune versus the flexalite probe? this sucks!

 

Update! Just found my cat scale ticket from when i weighed my truck and trailer


14,880.... so my trailer is actually 8880, not 7 or 7500 i said erlier....
