Been lurking here for several months and just pulled the trigger on a 22 RTL-E in Sonic Grey at the end of August. Very fist thing that I did was add an AAWireless adapter...once you go wireless it's painful to go back. Second was the dog shelf since there aren't any kids in the house and the pooch will have the back to himself most of the time. Today I took a shot at making some hooks to hang off of the seat supports when they are up. They came out pretty much exactly as I was thinking. Simple hooks from a big box with a back plate and some heavy fabric along with some sticky back Velcro. Hopefully dumping groceries all over the back is a thing of the past.
