Pinnacle Mt RV Park near Sutton, AK on the Glenn Hwy is an older RV park, but it gets the job done. It is close to the highway, so you do get a bit of highway noise, but it quiets down at night. There are full hookups and the sites are VERY wide and insanely long. They have 20/30A power only. The folks who run it are super nice. I never even looked for showers or bathrooms, and I think the only bathrooms were inside the lodge, which would close when the lodge closes. There is a lot of old farm equipment on the site if you like old iron. It's probably best as an overnight stay on the way to somewhere else as there's nothing really close in either direction. Price in 2019 was $35 for full hookups. They have some electric only sites too, which were actually pretty nice. The full hookup sites had nothing at them, so no table or fire pit. The pits may have been removed since there was a very serious fire ban at the time we visited. Lot is mostly gravel.
