I know your weather in SD and the desert rather well. Daughter (32) is a UCSD grad. I have relatives in Oceanside. I see your point.
We camp mostly in the central Sierras. Two years ago, on Memorial weekend, we got 2 inches of snow. Very pretty in the morning. It was all melted before 10AM. This was at 8,000 feet on the Sonora Pass highway. Highway 108 was closed for the season from 2 miles past where we turned off all the way to the bottom of the eastern slopes.
The year before we were at Bass Lake near Yosemite, at around 4,000 feet. We did not get any snow, but we did get more than an inch of rain. Riding ATVs and motorcycles in the rain and mud is fun, but cooking and eating in it is not fun.
Our first trip in the 24R will probably be Big Sur in December. I am certain it will be wet. If not rain then it will be dew dripping off of the redwood canopy.
We cook and eat outside as much as possible. Sometimes the weather does not co-operate.
Our first grandchild was born on September 1. For the next 5 years or so I will not be surprised tht in bad weather he would rather be in the MH with grandparents than in the tent with his parents.
