I know it seems like a fairly easy task, and I am confident I have the ability and tools to do so, but was looking for some suggestions. I have an outside gig coming up next month for a benefit, and the budget is next to nothing so I'm thinking about building a riser myself and renting it out in the future when desired. It will be kept in my 6x12 trailer. Not really sure on dimensions, but I would like to keep it as light as possible without sacrificing the rigidity of the structure. I was thinking of somehow make it fold into half with casters so that it can be rolled and will take up less room in the trailer. I was thinking 10-12" in height would suffice. Any suggestions on the matter?
