Joined a year ago, just finding time to get back on here!

I saw a pic of a rack that someone built to store/stack 2 quads! I am looking to do something like this as cheap as possible, and as quick as possible.

Does anyone have any pics and details they can share to help me out. I really don't want to make this thing too bulky and in the way, just want it in the corner of the garage so I can make some room this winter!

Anyone that can point me to a thread, or a user that can help would be great!

Thank you!!
