Yes you do... but at this point if you wait another month or two the garage will be really put together by the time you get here.....I have a few things in the works that are above and beyond what I already have going and hopefully I can have some heat soon.... that's if churchmouse and I can work things out.... He may not have the best of news once he comes out and sees what he is getting into.
With the holidays upon us I would say you'll have everything buttoned up by the time we make it there. All good. It'll give OG lots of ideas for our cabin.
BTW - The numbers crunched above regarding LP consumption are probably to maintain a building closer to 72 degrees. So, I bet your costs will average out to less than that $1 / hr.
