We have a 1 1/4 mile common trail. The first 1/4 mile is not bad as a more recent full time owner has a small dozer and a small/mid sized UT with a box blade and that section is level and flat. But past their place the trail climbs steeply with many turns. Again, this is a common (private) trail crossing private land, a half mile passing through BIA set aside land and you know that owner does nothing to their part of the trail. In addition there is no grading to be done on the mile to our place or the various sub trails. There are very large stones to literal boulders imbedded in the trails that hold it intact. Mess with that and you break up the base and it becomes a bog that severely and quickly erodes. So the only repairs are adding material and not cutting except for maintaining some drainage laterals. Lastly, many ditwads refuse to lock front hubs or engage their 4wd which should be done all year around when climbing so they spin tires and throw rock/fill off the road. Some people try to come up the road to other places in their little front wheel drive city cars leaving pieces of plastic along the way. It's hilarious.
We consider the road condition a blessing. It seriously discourages snoopers, cruisers and kids exploring. I only post this to say that sometimes a nasty road can be a blessing in disguise.
