You should have no problems getting in at all. Very easy to access area and the sites are large, flat, and most are easy to navigate in and out.

Yes I think so. The trick is to come in and exit from the east side. It's a beautiful area snd the night skies are spectacular.

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.

Easy entrance from the east. Large parking area on the right at top of hill. You can park and scout from there, or there are several large flat areas on down the road. Several areas from the west end as well but a few gullets to cross in the middle. I made it in from the east side with a 38 ft fifth wheel with no problems.

From the eastern entrance you have about 5 miles of road accessible by most RV (including your unit). Same from the western entrance (at bottom of Moki Dugway). In between is a stretch of road that is navigable by most cars, trucks and SUVs but definitely not by a motorhome or with a longer heavier trailer. I would enter on the east side and park in the pullout just after the river crossing and scout for a site that you want to use and then bring in the motorhome.
