AKO,
You might check out Bordertown Casino & RV Resort, located northwest of Reno on 395, approx. 10 miles from the junction of US 80 & US 395. It is out and away from the busyness of downtown Reno, yet close enough if you want the Reno nightlife.
Last year's rates: $20 to $30.

We live about 2 hrs northwest of this RV park, and have stopped once to check it out, but have never used it. It looks nice, we've just never needed it.
Enjoy your trip.
