No we were alone. I remember seeing a white lifted 80, a built 80 camped at Sanger Meadow...maybe two- one w a roof tent.
then a few more 80s running around. It's the most Toyota's i've ever seen up there. Even a 200 series HE!
A lot of 100's too. A nicely built 60... blue, I think. A lot!
I'd love to but my 80 needs some love. I loaded it to the gills and ran it hard. I found my air locker seal is leaking, knuckles are leaking, and I really need to change diff/tcase oil. Too many hard off road miles and water crossings I guess. But then again, that's why I bought it!
I find these two sites have the best weather predictions. As far as when the snow falls it changes every year but Mammoth usually starts getting snow by November so I'd say if you want to get up there plan in the next 4-6 weeks. We really lucked out with lows in the 50's this trip. We took a labor day trip a few years back and saw lows in the teens at night so be prepared if you go up there between now and when the snow starts to fall.
I still need to post up my report. That said, I would definitely recommend doing this route with another truck. It's a long way to help if you break down. Or, bring a nice down hill MTB if you go alone.
