Welcome to MBc, Mannhouse. Now that you have introduced yourself, be sure to read all you can, including the 'Stickies'. They contain a lot of information. For example, Sticky #1 under ‘Introduce Yourself’ has 20 or so links to “How To…” threads, and important pages for you to follow. Sticky # 3 has info on forums, how you are expected to conduct yourself, and where you might find and use various features. But, read all of them, and be sure to use the search feature. If you are still stumped, post a question in the proper Forum.
Be sure to keep us posted on the progress of your build. A sidecar seems to be both a challenging and and rewarding project. I don't really know what Forum your 'build Notes and pics' would fall into, but we can figure that out later...K? Good Luck.
