Good info.
Going to watch craigslist and freecycle for racks.
It would be nice to find a hitch-mounted rack that can lower so access to my mini-SUV hatch would work.
Once I get my tools setup at the house I could probably build you one of those in the future... could even make it able to hold a box or extra fuel can too, etc

I`ll let you know when I get all my welding and metal working tools setup probably a month or so as I have to run the electrical, insulate and drywall the garage prior to bringing it all in.
