We stayed at a handful of KOA's along the way to Ouray. The one in Amarillo is unfortunately situated next to 1) train tracks 2) busy highway and 3) a local airport runway. The giant jack rabbits are a sight though. KOA's have one saving grace over many state parks...unusually well-kept bathrooms and showers and fairly cheap rates. We stayed in one near Little Rock that you could have eaten your breakfast off the bathroom counter and been perfectly safe.
We stayed at a couple that appeared to once upon a time have been KOA's now privately run. They were adequate but not nearly as maintained as the KOA's. The better private ones we stayed at were in Sante Fe (recommend bypassing Albequerque) and in Durango. Quiet and scenic.
If we wanted to get on the road a little quicker the next morning, we would just rent a little cabinette for a few dollars more and save ourselves the trouble of deploying a tent. Still cooked on our grill or firepit.
We avoided hotels for the crappy experience they provided for the dollars they wanted in exchange. At least in a KOA or private camp you were still outdoors enjoying nature, be it in a tent or cabinette. And if you need to still "plug-in" all the ones we stayed at (KOA or private) had free WiFi.
