Where to stay near Mountain Pass, Ca?

[Gwenne & Len]

So I found a route someone here mentioned a while ago - over 190 through Death Valley.....I called an RV park in Pahrump - one drives through the mountains to get there. So, is the route through Death Valley and down to Las Vegas through the mountains? I"m really trying to avoid mountains when we can.......Tehachapi sounds interesting, maybe worth the extra driving, and it looks like there's no way to avoid Las Vegas.
