I believe that is it JimR1. I never have stayed at either one, but some friends of mine stayed at a KOA right across from one of the Marine bases. But actually that is not part of Barstow. That is the little town of Yermo, CA.
I honestly believe that the only place in Barstow is the one across from the drive in theater. I do not believe it has many RV sites. It is kind of hidden if I recall. Now Off I-40 east of Newberry Springs, there is a site there which I believe it just opened a few years ago. It is on the right side going east. Most of the RVers stop at the new Super Walmart. It has a big parking area where lots of motor homes stop over night, and also some big trucks stop I guess to get some shut eye. It does get hot here in the summer. Right now it is around 100 degrees. We usually leave on our coach in the summer and go up into Oregon and Washington staying on 101 at the TT Resorts right next to the Pacific ocean, but this year with the Coronavirus we decided to stay in our stick house and hopefully things might get better by the fall so we can start traveling again.
