The boards are an idea if you can get it on them. I have known people use old carpet rolled out over the mud. Anything to get traction. It would also give you a chance to get under it to fit ropes.
Worth taking a few shovels to level center ruts out and save the body bits.
As so many have said, if it wasnt so far I would be happy to lend a hand.
