I have heard nothing but good things about them since they came out.
Downey you are probably thinking of the Toyo Open Country ALL terrain, which a lot of people don't like.
When I had my ranger they only had the 33x13.50, no 10.50 or 12.50 otherwise I would have have them a long time ago on the Ranger or Sport Trac.
Actually I ordered a set of them in 35x12.50R18s for the F150 but I found out that the side lugs would rub on the control arm with stock wheels so I canceled the order and got KM2s.
