Facebook group also includes Burros as the two are very similar. There is a "files" section there with some Burro
specific info. Look in the Document Center on this site also as there may be information there.
Edit: there is some info in the document center, sales brochure, manual, and assembly manual. Burros could be bought in kit form or fully assembled. Click on Burro in the list of manufacturers at the bottom of the page in the document center.
