I just ordered Dunlop Radial Rover XT RV's from Discount Tire. We'll see how they compare to the mismatched Continentals that are on there now. The back tires are the original EcoPluses with 43K+ miles on them, the front tires are standard ContiTracs that I suspect the original owner put on before they turned it in at the end of their lease. In any case, the reviews on the tires say they're quieter and have better traction than the Continentals. Discount Tire had them rated 4 or 4.5 stars compared to 2.5 for the Continentals.
