Cabela's in Lehi, UT

The Cabela's in Sidney, NE is their flagship store, and they have a real RV park on the property. 37 sites and even a corral for your horses. W,E and dump station. $30/night. Private, lockable bathrooms with showers. Very nice.
On one visit, I stopped to say something to the greeter at the door and wound up talking to him for more than an hour. He was one of the originals that started the business by tying fishing flies and selling them by mail order. He told me to drive into town and look at the door on the second floor of a brown building. Sure enough, it was filled with small holes. That's where Cabela's started. When they got bored, they shot arrows into the door and the holes are still there.
I spend entirely too much money at Cabela's, but I've never bought anything that wasn't first class. Lucky for me, they don't have a store in my town.

We have stayed there 3 or 4 times. They asked us to park out back where they have a dump station and potable water. One time, we were the only ones there when we went to bed and awoke to over a dozen and a long line for dumping. Should have done it when I had the chance.

I called them for you. Overnight parking is okay, water and dump station are available.
