Mammoth Lakes, CA?

[Creampuff]

Planning to tow my ‘16 25’ Int.Signature up to M.Lakes in late May. The elevation I hear is over 7K which is a little concerning. TV is a 2014 Cayenne Diesel so it’s up to the task but just looking for anyone with advice who may have done this trip. I’m anticipating high altitude LPG issues , but is there any high percentage grades climbing up 395?

Our son and his family live in Mammoth Lakes. We traveled with our 2014 23FB Flying Cloud in June 2021 without any problems. Tow vehicle is 2012 Toyota Sequoia. We drove from Aptos, CA over CA 88, Carson Pass, spending one night at Kit Carson NFS campground (delightful), one night in Bridgeport (visit to Bodie State Park), then 4 nights in Mammoth Lakes (G-daughter's HS graduation). Traveled US 395 south to Lone Pine, Alabama Hills for 4 nights. CA 14 to CA 58 (Tehachapi Pass) to Bakersfield, to Interstate 5, to CA 46, then US 101 back home to Aptos. We had a great trip without any incidents.

We were in Mammoth Lakes in our FC 30 in 2017 I think it was. 395 was ok for us; I rather got the impression it was made to interstate standards, which I think are limited to 6% grades? We stayed in Mammoth Mountain RV Park, which was fine. Very enjoyable visit.
