RV friendly gas stations?

Retired out of Temecula. Currently building in Murrieta. Spent a lot of time at the now defunct Bernardo Shores near Coronado. Family in Apple Valley. Very familiar with the area. Here's what we do for RV gas in those parts. Leaving SD, stay on 15 when going thru Temecula. The gas station at the Costco in Lake Elsinore is generally nowhere near as crowded as most. That should get you at least to the Lynwood area near Barstow. I'm sure there's still freeway construction around the Devore/Cajon Pass area. That route would have minimized it last month when I was thru there. If you don't belong to Costco or prefer to take 215 out of Temecula, there's a station that should be RV friendly (though I have never used it) at the Ethanac off ramp between Menifee & Perris. Easy on & off. There's a Sam's Club with gas in Murrieta just off the the 215 at the Murrieta Hot Springs Road offramp, but lately it has just been incredibly crowded. There's also a truck stop place on the 15 very close to where 395 peals off just over Cajon. Never used it though. And, if you belong to Costco & need gas shortly after leaving SD, the store in Escondido has gas, but can get crowded. Unlike many Costco's, there's a lot of room at the station though.
