I have been web searching for things I would consider unusual, like sheet aluminum, and yes, a local supplier is not available. I did locate regional, but the shipping is twice the price of the material itself, so I am still shopping. I have found retailers or wholesalers for most of the materials, so I am curious as to the difficulties you were running into. To say that I'm ignorant to the possible downfalls of construction would be the understatement of the year. I tend to view cost and time the same way I think of home improvement; multiply everything by 2.5 then add a month and another hundred bucks. But then again, I can't make dinner without going over budget - mostly because I love adding that little extra something. My fear is that a little extra on my camper will amount to gobs of cash.......... but then again, I'd just spend it elsewhere anyway. So if you have any insights on materials purchases, or links to material supply outlets, please post them. Thanks to all for the warm welcome.
Ask not what your country can do for you; they're already behind on their bills and next month ain't looking any better.
