Bikes AND a Cargo Carrier

We really want to bring our bikes with us for this trip the the Grand Canyon. We also want to bring a lot of other stuff. There's not too much room for storage in our little Toyota Winnebago Warrior. Now that the back end is all reinforced and beefed up, we want to use it! Can we fit everything we want?

We lost a little bit of space in the cargo carrier because the bicycle wheels have to go in the top a little. Not much real estate back there.
