I've driven from Lone Pine to Las Vegas in my 85D. It was close but I made it with 37 miles left by driving 55-60 mph. Route through Death Valley and Beatty, NV.
On the return, we drove through Pahrump and Ryan and stayed overnight at Furnace Creek (RV charging).
About the same distance either way (225 miles). You can make it if you watch your speed.
If you're nervous about it, you can go through Inyokern, Barstow, and Primm SCs but it's about 75 miles longer.
Death Valley is a beautiful drive.
