Found the perfect trashcan for the Outback, a Rubbermaid Slim can, fits right between the shelves and the door.
For years I've used the yellow wheel chocks from Wal-Mart, and they've worked fine. But the BAL Deluxe wheel chocks not only chock the wheels and prevent any movement they also help to stabilize the camper while setup and act as another set of stabilizers.
We built a new house in 2003, which we love. The only problem is that they installed the gas meter on the side of the house where we park the camper, making it very tricky to get the camper in and out safely. To make matters worse when we put up the fence we had a 10' opening for a 8' trailer, leaving about 12" on either side when we back it in our out. After a few runs at it, and the flared tempers as my wife and I tried to communicate and negotiate the corners it was clear something else needed to be done. Parking the camper someplace else just wasn't in the picture. So we purchased a Power Mover instead. Its not cheap, but it moves the camper great and ends the yelling, best of all its easy to move the camper and adjust it so we can access the camper.
Its a tight fit, but with the power mover we get it in and out easily.
Setup is easy, includes 110v and trailer brake switch too.
It moves slow, but it does the trick.
Seller recommended using the bracket (shown) so it won't interfere with the
Equalizer WDH setup.
