First, you need to decide whether you want to take the rig down the EXTREME gravel switchbacks of the Moki Dugway (UT-261 between Muley Point and Valley of the Gods), the most direct way to get to MH. Usually not a good idea for motorhomes, but 36' might just (barely) make it. WITH the jeep, not so sure. If not, you'll prolly choose UT-261 N across Cedar Mesa to UT-95 just E of Natural Bridged NM, then E to US-191 just S of Blanding & S to MH, which is all paved. Next, I'm not sure precisely what you mean by "sites". An actual campground vs. a "campsite" (which I define as a place you can camp, but not necessarily named, established, and usually without facilities or improvements.) Depends a lot on what amenities you require and what you're willing to pay for them. Also, Don't know if "does not well on dirt roads" means absolutely NO gravel, or just minimizing it. This is tough country for the former, but good for the latter. Given that, I'll give this a shot: Don't know your itinerary, but camping at Muley Point is pretty incredible, itself. (But it is a short gravel road off 261 to get there. Now to your actual question: BLM Sand Island, on 191 almost along your route, is a nice, usually not crowded, inexpensive federal campground. It's just barely W/S of Bluff, where 191 splits off from 193. For a quick few hours of sleep (more parking than camping, which I often do), there are a couple of pull-offs between the river (San Juan) and MH. You can overnight right near the actual (geologic) Mexican Hat, off those gravel roads. The road through Valley of the Gods is gravel & I wouldn't recommend for your rig (YMMV) & the pullouts are a bit small for you. There is camping at Goosenecks state park (I realize you asked about federal, not state) & the view is amazing. I can't think of any other USFS/BLM actual campgrounds. If I see any, I'll update this post. Don't know your fuel mileage, but remember to take into account the distance between services. I've run this country for years & found myself uncomfortably short two weeks ago. It's good practice to top off when you can & forget about trying to save a couple cents per gallon. On that note, the cheapest gasoline (and usually diesel) in the area is in the tiny postage stamp of Ute reservation called White Mesa (good luck finding it on maps!) about 8 (ish) miles S of the UT-95/US-191 juction 4 mi. S of Blanding) {Rez gas is sometimes cheaper, but not always. A common practice is to charge going rate and offer a Native discount with ID card. Some, like the White Mesa band, make it cheaper for all.) Hope this helps. Feel free to contact me for more, better, or more detailed information.
