To do list before winter

Today I went up, checked on everything, cleaned up a little bit of the lot since some of the styrofoam pile blew around, and started to build a checklist of everything that needs to be done before winter sets in, since fall came and is going fast.  When I left for France, we were consistently in the upper 80's and my air conditioner was still in use.  My windows have not been opened since I returned, and today is the first time my apartment has hit 70 since I got back.  Since I will be gone again next week, time is rapidly running out.  I had originally figured with how warm we had been that I would be able to work well into November, but that doesn't appear to be the case anymore.

Here is the list, roughly prioritized (with any limitations that might affect it):

1. Buy a new truck.
2. Install the outrigger supports on the shed.
• Needs to be done before snowfall.
3. Install the inter-rafter supports for the ridge board.
• Needs to be done before snowfall.
4. Rework the pilings for the shed.
• Needs to be done before the ground freezes.
5. Remove the trailer tanks.
6. Sand and paint the trailer.
• Needs to be warm enough to paint.
7. Weld the new pieces onto the trailer.
8. Put gravel down in the driveway.
• Preferably before the ground freezes, but not required.
9. Install driveway markers.
• Needs to be done before the ground freezes.
10. Stabilize the mowers.
11. Cover the piles and stuff on the slab.
• Needs to be done before snowfall.
12. Electrical panel work.
• This is a nice to have, I will be losing the generator before winter.
13. Install the mailbox.
• Needs to be done before the ground freezes. 
• This is a nice to have, strictly speaking it is not necessary.

It is foliage season here, so it was a pretty drive up there, though my specific lot hasn't really begun changing yet.  I did however see a pretty blue butterfly enjoying the sun.
