Only about a dozen sites and they all seemed to be occupied by long-term residents.
I went to check out this RV park after reading the single negative review. I phoned and was told it was behind the Nugget Casino and would cost $35 for my class-B van. I drove by it and found it was clean, new, and basic. No long term residents were to be seen. I'd stay there next time I pass through Wendover.
We stayed overnight Thought $35 was a little steep for being very basic but had 50amp full hookups and I was told by the hotel front desk that they had security go down once an hour. Had good water pressure. Only one long term rig and then only one other rig. I thought they should have a shuttle service up to the casino!
