First RV and a few questions

[ttikalsky]

After 2+ years of research and searhing I finally brought home our
first RV, a 1983 Bluebird Wanderlodge FC 33. Can anyone help me with
a few questions?

1) Where is the leveling jack fluid tank? The jacks won't stay
extended and I would like to check the level.

2) The rear view camera is not working (the part that mounts in the
back of the coach) is it worth fixing or am I better off replacing it?
Any suggestions on who or where to fix or replace?

3) The cruise control is not working, any suggestions on where to
start diagnosing the problem?

4) The LP/CO2/Smoke detectors alarms are going off (monitor in galley)
for the center and rear furnaces, but the gas is shut off at the main
valve. Are the sensors replaceable or could they be cleaned? Does
anyone know if they operate by opening or closing the circuit when gas
is detected?

5) The cab a/c is not working. Is it worth fixing or will the two
roof airs keep the coach cool in 90 degrees at 90% humidity when
driving?

6) One of the roof vents got broken, when I leaned on it. Are the
Maxair convers decent or just a gimick? Is it worth getting the one
that keeps the rain from entering?
