Notice the edit! I do not remember the precise road we used, but a few years back we did a day trip in my wife's XC-90 from the wine country in Temecula to Anza- Borrego. The grade we took, I would never do in our 37' Class A. One of the RV parks had a sign warning of the grade. They told me they verbally cautioned people about it. I think there is a high probability that the above recommended route has you using that pass. On our return trip we came around by the Salton Sea back to Temecula. A lot longer, but it is what I would do from Temecula in an RV. Might I suggest you call the park you are going to, or contact Cal Trans or the CHP office that has jurisdiction in that area to be sure.

I am utterly perplexed by this response.I and thousands or perhaps tens of thousands of other RVer's have been running up and down the Montezuma grade since it was completed in the mid sixties with no problems at all.

With billions of miles probably expended every year on 6% grades of the interstate highway system it puzzles me how an 8 percent grade suddenly should not even be considered as a route in and out of the Borrego Valley.

But then I don't hesitate to drop down out of the north side of Big Bear on a long 16 percent grade either so maybe it's just me.

All RVers of course have to use due diligence when choosing their route through mountains but I do not hesitate to recommend the Montezuma grade.
