I didn't have any problems with my RD radiator in Moab this year. Made a custom aluminum shroud to hold my 2 10" electric fans (not sure what brand, got them used from a friend) and everything has been great. Holds temp at just below half gauge driving around without the fans, and stayed the same on all the trails with the fans on. I didn't run the A/C at all in Moab thanks to my blower motor being dead, but I am confident it will be fine this summer.
