<sigh>... Where did that come from?
Anyways.
Rubicon is a bit south and a bit west of Lake Tahoe.
It's not friendly to full-size rigs, lots of tight spaces, even on the bypasses. I know you can get a hummer through it, but it won't come out unscratched...
Expect body damage on anything bigger than a Jeep.
Now, owning a full-size Ram, I haven't exactly been down it. I know others that have done parts of it with full-size rigs, and kinda made it.
