We pulled our A122BH over Sierras on Hwy 4 to 395 last summer, followed 395 south to 14 to 58 to cross back under the Sierras. Incredible country. Hwy 4 Ebbetts Pass is incredibly steep, incredibly twisty - hairpin turns, incredibly narrow, single lane sometimes....and cyclists sharing the road. Grover Hot Springs, Bodie SHP, Mono Lake, Mammoth Lake, Owens Valley, Lone Pine, Mt Whitney. Did I mention it was an incredible trip?
No trouble towing. We drive a E350 Ford van.
