I travel on roads similar to those ... but not in the RV. We do volunteer work off some steep un-maintained ranch mountain roads in the remote outback part of a CA state park. We have special permits to drive in there where normally only backpackers and mountain bikers are allowed.
It's a lot of fun in 4X4 compound low with the pickup. A bonus is fishing in the remote lakes/pounds back in there for wild bass that rarely see a hook. They jump on the lures with sometimes multiple strikes per cast.
