I am just trying to say know your rig know your limitations. Nothing wrong with working through a tough trail, part of the fun. I have had my share of tough trails but I have never left anything damaged (trees) or trail rutted any worse that any other narower rig. I just do not want to be kicked off trails because my axle width is 80". Not fair when I do not touch any trees and I do my part as a user and clean up as I go and take garbage home that is not even mine. I will help anyone on the trail at any time for as long as it takes. As far as funding it is not all funded by donations only. Their are funds from the forest service for federal land and state for dnr lands that go for this to. That is how and why the patrol them. I will agree that joining a club is the right thing to do and is my hopes to get to in the future but with two kids right now and not alot of time to even wheel but a few times a year right now not in the cards but in a few years for sure.
then this is the absolute minimum you should be doing to help promote your hobby.
