I have decided that i have become bored of my Mini ramp so now I am expanding it. I am adding on 8 more feet, making the total width 20 feet(wow!), raising the extensions up to 6 feet, and also adding a roll-in(OMG!). I will be posting progress pics as I go along, so check out my project page, (bens mini ramp)and let me know what you think!
Here are some CAD drawings I made of the ramp when its finished.
