Meteor Crater RV Park
Meteor Crater was our first stop when we returned to the life of full-time RVing. We were surprised by the campground, because after nearly 7 years in northern Arizona we weren't used to green grass and trees in local parks. It is a gated park, so you must check in at the convenience store. There is ample parking while you wait. They do close the gates for the night fairly early (7:30 when we stayed in March), so you don't have to deal with many late night arrivals.
You can opt for FHU or just W/E sites, which come with a picnic table and some have shade trees.
As you may notice, some of the sites, like the one we were in, are fairly short so we had to park in front of our rig. They do have larger pull through sites to accommodate rigs of any size. There are plenty of sites, but it does fill up in the summer as this picture from their site shows.
On the downside you do hear road noise from the interstate all night, and trains come by frequently - so if you are a light sleeper, bring ear plugs. All in all it is a good place to stop for the night, so pull in and check it out. If you are going to see the crater too, make sure to go there first and you will get a coupon for 20% off for one night stay at the park.
