I have a Forester, it is a good rig. Make sure you have an external water pressure regulator and use it (about 8 bucks). Some RV parks have high water pressure and anything over 40 PSI going into the rig could blow out the the water connections. Make sure you have the right toilet paper, its not the same stuff. I would visit the north rim of the Grand Canyon, not nearly as commercialized as the south rim.
I will add to this, put the pressure regulator on the spigot, before your hoses. I almost blew out a hose on a campground that had 70+ PSI of pressure.
Had my pressure regulator after the hose at the RV, and went and checked it in the mid-day heat, and the hose had swelled to nearly double it's original diameter. I moved the regulator to the spigot, and everything went back to normal.
I was told to use it at the RV, but that won't save your hoses.
