I've built a cpl boat houses on water...millionair crowd...sorry no pics.Reason for posting however is your "deck" or maintenance issue........go snag some Safeway scaffolding....they come in 2',3',4',5',and 6' heighth's.Get corresponding braces/decking and if you don't want to fab up the stairs,for a price you can buy them from same man. as scaffolding.Anyhow make your deck out of them...when not in use pop M apart and throw them behind shop.
They also work as intended and can assist greatly for in the shop maintenance chores,especially with their locking wheelset.You can buy them @ tool rental places that are vg cond. used.This (rental joint used price)is your $$ gage when buying them on open market,CL,Evilbay,ect.BW
