There’s not a whole lot of roads up high in any national forest or BLM. So any information you get on a public forum is really gonna narrow the scope. And just because you’re asking a question doesn’t mean there isn’t 300 other people reading the answers.
I will try to answer your question in general though. Check with the local management agency and use something like on X maps to be sure of what’s private property or closed for the season, etc. As far as road conditions go if it’s an old mining road, you might want a high clearance vehicle with some skid plates if it’s a logging road you’re probably fine to take a Prius down it unless weather hits.
