looking for ideas (recovering camper from mud)

no diff lock on the tractor and no power down on the bucket only power up and pin to dump. I have no doubt the truck will get to the trailer. more worried about getting it out when the trailer sinks. as long as I can keep the trailer up enough I should be fine. just need to avoid burying the axle since I don't really want to ruin the brakes or worse yet tear off a perch
