"Great products what started out as an idea to prototype a future build probably out of 8020 with cabinets turned into a definitive, lightweight solution. Started with a simple bench that allowed an additional slide out bench bed. Then converted to a lower second bench for a dresser refrigerator and toilet. 

Now building out a back seat platform-simple and with adjustable height via feet. Bonus to create rigidity, the 3/4 pipe fits over the 18mm bolts used for the seats (removed) perfectly. Lastly spring clips will be placed on the wood for the back set platform for easy removal." - David
