Sounds like your chassis AC is in better shape than mine!

The roof ACs are much like a household 'window' unit, but modified
for the roof mounting. A tree branch KO'd my front AC (on my maiden
trip home) and my rear unit was only so-so... I replaced them both
with Duo-Therm 13,500 BTU High Efficiency units. These units only
draw 10 amps instead of 14.4 and therefore save a bit of electricity.
While they're taller than the "Penguin" model that comes on many BBs,
I already have a King Dome (TV antenna) that sticks up taller, so I
had no real loss of clearance height. (Interestingly, I think the
King Dome pushed the branch up so it whacked down even harder on the
front AC ... apparently the King Dome is fairly sturdy and wasn't
damaged.)

The auto levelers are a great convenience. The sensor may be located
in the front basement compartment right were the top and front
bulkhead meet. Mine tends to stop leaving the right side not quite
1/4 bubble high. I'm told that this is "within spec" -- and that it's
quite complex to properly adjust the sensor. Once the automatic
leveling is complete, I tap the down arrow for the right side and it
brings it almost perfectly level.

The "official" approved tire is a 12R22.5. Some have converted to the
315/80R22.5. Just be sure that the proper spacing remains between the
dual tires. The size difference may affect the accuracy of the
speedometer.

The 315s may allow you to run with slightly lower air pressure (for
the weight) giving a smoother ride. Review the weight tables on the
tire manufacturer's web site. Weigh your coach (fully loaded) to
double check for proper inflation.
