icechest slide out

i am looking for ideas for an icechest slide out that will allow me to slide out a 120qt igloo out from under my seats behind the console. i only have about 1.5 inch clearance above the lid. i am not interested paying the outrageous price for a manfactured slide.

i have seen great responses in the past here on 2cool to solve issues of other boaters.

any ideas are appreciated.
