I would run the 5-20 Royal purple, I pull a 30' travel trailer in the southern heat with no issue at all. I grow up in Southern Cali in the high dessert and move to Alabama and it gets every bit as hot here as it does in the high dessert of cali. It's about lubrication and how well the oil stays on your bearings and maintains the clearances between the bearing and crank,cam. Also a full synthetic group IV will take the heat better and disperse it.
