Does anyone have experience with Toyo Open Country M/T tires - on a truck with a truck camper?

The Open Country's are the recommended tire by Les Schwab Tire Centers, for the HD truck/camper - being used off-road occasionally.
- - am concerned about how much road noise these have when travelling down the freeway, though.

(Yes, wishing for the best of both worlds - quite ride on the highway, with excellent off-road handling and safety on rocky roads...)

I just put a set of the Wild Country XTX sport's on another, smaller truck (toyota) (no camper) - and they're great so far, little road noise...
Thank you.
