330 was actually my preferred route to Big Bear. Famous picture from years back of a Bayliner Trophy and it’s tow vehicle, one of which was hanging off the cliff. (Same pullout I always used!)
We’re currently up in the Gold Country, using mostly 49. It’s infamous for steep long grades & tight turns. Just drove from Manteca to Black Oak RV outside of Sonora, then to Jackson Rancheria. I found it nowhere near as challenging as those associated with Big Bear or Crestline.
I’d suggest you download the app ‘Mountain Directory’. Details troublesome grades, etc. It recommends 38 to access BB or Arrowhead. I also use the ‘Motor Carriers’ Road Atlas’. It id’s routes recommended for 18 wheelers. It identifies no route to get up there.
You might consider what I did. Drove my tow vehicle up just to see.
