Easily. Depending on the time of year, the road can be washboarded, but the county usually keeps it in pretty good shape. I’ve seen huge motor homes pretty far in. As Dave said below, your best bet is to enter from the East side, and park ASAP, using your tow vehicle to scout your best location. After 5 miles or so, the road gets pretty twisty, you don’t want to drag your trailer through there.
