DonTom, a friend of mine in Sacto has a Leaf which works for about 95% of his daily driving (but he only has ICE motos) and he said that when it is time to go to Reno to see his grandkids, the ICE car gets gassed up, the Leaf just doesn't work . I see he's not the only one with a range issue for that trip.
My Tesla range is accurate even on the freeway at legal speed limits. I could easily go from Reno to Sacramento AND perhaps make it all the way back on a single charge. But ~280 miles would be cutting it close because of the hills and such. My range is supposed to be 310 miles and is fairly accurate in most conditions.
If he doesn't mind waiting there are MANY places to recharge between Sacramento and Reno. Auburn, Colfax, the Shell gas station at Cisco Grove ($3.00 but Boreal is free and just a few more miles--but sometimes the gate is closed--not an issue for E-MC's to go around the gate) and also Truckee as well as Reno.
I would think the leaf should work fine for getting to Reno. I have taken my SR with Power Tank from Auburn to here in Reno, but I did recharge at the summit. But I could have made it one a single charge as I was at around 50% SOC at the summit and it's all downhill from there. 99 miles total, but lots of hills and faster speeds. I also rode it back to Auburn. I took a couple of Zero quick chargers with me, one in each saddlebag with all the required cables.
