BADDOG,
I coil my genoa sheets and bungee them to the furled sail. Use what was your headsail halyard and clip it to the fabric loop on the top end of the sock. Get the zipper started and while holding the zipper pull the halyard as if raising a sail. When you run out of zipper your genoa should be completely covered. My sock has laces on the bottom end and I tie it off under the furler

When I put on my sock I have to reach pretty high...about as high as I can reach...when I start zipping it together. I have to get the top of the sock above the fattest part of the furled 150 Genoa. If I start the sock too low I can't get it past the fat bulge.
I use the jib halyard as my sock halyard. And when sock is off I connect this halyard to the bow pulpit where it kinda/sorta acts like a second forestay. Every now & then this halyard will start to wrap itself up in the Genoa as I furl it. But can normally be fixed from the cockpit by just unfurling and then furling again a little bit more slowly until you have enough furled that it can't get tangled.
FAAbaddog,
You say you boat is on the trailer, is your mast down?
If so, then, and for now, you really don't need the jib/sock haylard to get the cover on the genny.
Just lay it under and zip it up.
But do take note if your genny isn't laying straight for your winter storage.
Any longish time bending of the furler will result in those bends having a "memory" when you raise it next spring.
The long plastic thingy seems to take a "set" over time.
Getting it straightened after it occurs is a semi-serious headache that's so easily avoided upfront.
Most folks tie/bungee the covered furler along the mast (acting as a splint)and add a five foot long 2X4 (or whatever) extending the mast to keep the lower end of the furler from drooping/overhanging at the pulpit.
Keep it as straight as you can.
Even the little jog that occurs when the furler crosses over the spreaders should be kept at a minimum.
