There aren’t many good stopping point midway between Utah & Oceanside if you want to overnight in a RV Park. For our two-day drive home we wanted to have an early arrival day 2 (Oct 9th) so that meant driving longer day 1 (Oct 8th). If we stopped again at Thousand Trails Las Vegas, our day 2 drive would be 6 or more hours. So we stopped in Las Vegas just to fuel and have lunch, then continued to Barstow. I thought stopping at the north Las Vegas Maverik gas station truck stop would be easy but it wasn’t. Because of road construction, the exit detour takes you away from the gas station, so a u-turn is required. Fueling there wasn’t easy either since all the truck pumps were diesel. Non-diesel RVs fuel at the auto pumps which is fine but required us circle back around.
When we drove home from Utah in 2021, we stayed at the Barstow/Yermo KOA. It’s a good stopping point about 6hrs from Utah. So we booked a pull-thru hookup site with electric & water for one night. We’ve stayed at other KOAs and this one is pretty drab when compared to the others like Monterey/Santa Cruz KOA. But the site assigned to us this time was a lot nicer than last year’s, with trees and closer, cleaner restrooms.

There are other options if you don’t mind boondocking but with the +90° weather, we like having an electric hookup to run the A/C.
The Flying J Travel Center in Barstow or Peggy Sue’s diner parking lot in Yermo are free & pretty safe but noisy. You can also find BLM land along the 15 but we prefer to stay where we are more comfortable. Another affordable ($25 full-hookups) option is stopping at Clark’s Mobile Home & RV Park in Baker. We stop there last year on our way to Utah. It’s essentially a parking lot just off the 15 in Baker with full hookups but no other amenities. There is a market and a few restaurants nearby.
