I ranger on 18 miles of beach and sand trails in the summer and we have visitors get stuck every day. We have winches on our trucks but keeping them working reliably when they are exposed to salt air 16 hours a day is problematic. We started carrying plastic traction boards and extra shovels and teach our visitors how to get themselves free. The boards work great.
To keep them from breaking under the weight you might want to check out the kind that roll up. They are sections of plastic blocks connected by nylon straps. Easy to store and don’t take up a lot of space.
