It's not that difficult.  Don't be a campsite pig and leave the site as you would have liked to have found it.  So pack out or burn all your trash...don't leave it in the firepit for me to pick out (I always do, if any is there). Do your business well away from camp and bury everything. If I can tell where your latrine area was, you can and should do better. Don't put nails in trees, don't cut live saplings for your tarp pole, don't stash firegrates or anything else, don't haul in non-native materials to build camp furniture (heck don't even build any with native materials).

I used to use log benches a lot more but camp chairs are so light and comfortable there's no need. I won't deconstruct what's there but I won't use it either.

It's been a long time since I've been to any campsite that receives even moderate traffic that doesn't have at least a couple nails in trees. If they are there, I'll use them. If not, I have bungee cords and/or rope that will suffice for me to hang anything I need to hang.

If you cut any live saplings/trees for any purpose, they are getting immediately dragged way back in the forest. I don't want to have to explain why it's there if the ranger shows up.  Collapsible tarp poles are very light and a lot more reliable.

If you stash grates, lawn furniture, etc. I will pack them out if it's reasonable for me to do so. The last day or two of a trip, it's a virtual guarantee I will do so. Early in a trip which involves a lot of travel/portages, I'll probably leave your crap stashed well out of sight but not too hard to find if you look. I don't need/want to carry it all over the Q.

I will reconstruct the firepit to suit my needs if it doesn't already. Some are completely ridiculous. Most are fine even if they could be a lot smaller. I mostly cook on stoves but I do grill venison/steaks/fish so I just want a way to get my firegrate level and at the proper height.

I do appreciate a nice flat/level surface for camp stoves. I've seen all kinds of rocks used for this, some work great and some don't. If it doesn't work, I'm moving it out of my way. If it does the job well, it will still be there when I leave.
