Purchased last fall and then our fall season went south.  I'm over 70 so hired a young fellow to help put it together.  9 hours including ground leveling and building a wood frame base per manual instructions.  The manual is well written and I am seriously impressed with your parts packages and their labels - good job!  One question though - am absolutely flummoxed by the single shelf bracket supports on each side.  The two on the rear wall are logical and make sense but the single?????  Do you have some type of accessory that uses one support only?  Other than that good job - Thank You!!!
