Trying to Save on Energy Costs

I was up until around midnight last night replacing door seals, checking for drafts, putting plastic window kits on the windows, etc. I even closed off the vents to one of the rooms that we don't even use. Hopefully I'll be able to save a little bit on our energy costs this winter. Any of you with singlewides, you know how drafty they can be - not to mention how everything for a mobile home is a different size. I would like to be able to keep our power bill at or below $80 this winter.
