Once you have a wheel under the front jack you'd be surprised how easy it is to move , I'm assuming level ground.... The pieces of plywood will help, if the ground is spongy you'll need them under the wheels as well. We used the chains in the front to move ours on the driveway, we used wheel chocks and big landscape timbers, being careful to never go more than a foot or two at a time, momentum is not your friend in this case.
If you post pictures, there may be other creative solutions...
Would a front hitch on your truck do it? Inexpensive and useful in many other situations...
