We have a Sears x-cargo carrier that is mounted to our Sable Wagon. The cross bars on that is adjustable. The original straps were worn, and after trying other options, I ended up going to the dollar store, and purchasing 4 nylon dog collars (sized for large dogs). They fit through the fitting, and what we did was wrap the collars around where the side rails and the crossbars meet. The carrier itself lays above the crossbars. For lack of storage, we kept the carrier mounted on the vehicle, and it's been on the Sable for at least 4 years. There is no wear on the nylon dog collars and it is secure. The downside is it supposedly reduces our MPG, but on the flip side, it's easy to pick out your car in a crowded parking lot.
Shortly after purchasing the Compass this summer, I found a soft carrier, never used for a few dollars at a garage sale. I took it out of the box, examined it and read the insert. I doubt that it could be attached securely without the cross bars. Also, I wouldn't want the weight to rest on the roof. The other downside to the soft sided carrier is that it isn't waterproof. I would suggest an x-cargo. We bought ours used, at a yard sale at least 7 years ago, and I think we paid like $40.00 and it was worth every penny. We've gotten so much use out of it. Check Craigslist or E-Bay for a deal.
When we drive from MN to FL and back again, we pack a 2 night bag, for our travel stays, and the 2 night bags go in our vehicle. Our vacation clothes and beach stuff goes in the carrier and isn't touched until we reach our final destiation.
I've researched other options for crossbars, and it appears that we will be buying the Chrysler crossbars before our next vacation. The cross bars are one option that I wish we would have gotten when we purchased our vehicle.
