Ronald I have to negotiate a gravel road when I leave the parkway to my motor home barn, about 300'. Make sure if you have OTR to turn it off on all dirt roads, will make one big mess. at the barn my drive is 90' wide, needed because I have to make two 90 degree turns while backing into the barn. I graded the drive to a depth of 8" and installed 8" of compacted ABC, no problems with the soft stuff! Originally before the stone I would get off into the grass a little I would sink down 2-3" when dry. Have been stuck in soft dirt before feels like someone grabbed the bus from behind it stopped so fast. I do not go to grass camp sites. Gary
