Jon,
A couple things I noticed from the pic's: In addition to the hose that Ron mentioned, there appears to be a leaking oil pan gasket or engine seal. The gasket is no big deal, but a seal may be. Propane tank is pretty badly rusted; check it carefully. U-joint doesn't appear to have been lubed any time recently, so tie rods and upper and lower control arms and ball joints probably haven't been either. Mechanic needs to check for excessive wear. Finally, the brake rotor has rust all over it. This can happen if the unit sits for a while without being used, and it may just be a light surface rust which will wear off after a few hundred miles. On the other hand, the worst rust is usually UNDER the pads where you can't see it. If it's severe, the coach may not move at all initially, and once it has broken loose, you may get a pulsing brake pedal and brake grabbing when it hits those spots on the rotors, and may require turning of the rotors to get rid of it.
Not trying to scare you, but check everything carefully. Oh yes, and check the date and condition of the batteries; they'll probably need replacement too.
