I don't know about any of that. Derek is usually a straight shooter. I don't doubt for a second he bought it sight unseen for a low, low price. Model A's are pretty simple and a cursory Google search will show you how to do most repairs. And normally, no, he doesn't do these with a trailer following. In these wonderful, modern times we live in.... his Mrs. is nothing more than a phone call away; and she'll hook up the trailer and rescue him. That's actually happened when his purchase turned out to be a pile.
