pnichols, you should not have any problem on the Loop Road, at least up the north side to the top. We have not gone down the south side of the loop, some info states steeper and rougher than the north part. The road to the top from French Glen is very good, gravel but well maintained. Worst part last year was the 2 mile stretch from town to the turn out to the Page Springs Campground, very washboard'y. After that it was very smooth, low dust, wide.
Fish Lake CG can easily handle your MH. Our Jayco was aboot 27 ft oal, and my sons is 31 ft oal. We had no problem going in and out of campground or the sites we chose. We didn't go past or into South Steens CG, so can't comment other than it is somewhat horse oriented. DON'T attempt to go into Jackman Park CG, very small, limited sites with extremely poor turn around area.
