    Can anyone tell me how often the air springs should be replaced? Mine have some rubber cracks but look much better than most of the other RVs I inspected before buying this one. I have seen some really weatherd ones that have not given their owners any trouble, but I want to avoid issues without wasting my $...

    Thanks,

    I'll try and keep you posted as I figure this out.

    What year is your coach? Air springs have an inner and outer shell. They do crack. If it leaks, it will blow and you will know it.

    My coach is a 2000. Almost everything underneith is in remakably good shape. I just have no experience with air suspension other than on a car.

    Avalanchedriver,

    The cracking you see is pretty normal. I would not replace them unless you visually can see a problem or get a constant air alarm. My previous M/H a 00 Diplomat with 8 bags still has the original bags installed. When you park your M/H do not be alarmed if you have a small leak and you get corresponding body lean over a period of days. Like 730 mentioned small leaks do occur and they can be a devil to find. I have (quite possibly had) a small leak at the brake plunger could hear a hiss when parked and shut down. While here in south Florida I removed the panel by the driver (real PIA) and believe I fixed the problem. Won't know for sure until I air up.

    Should I be lowering the coach when not in use to relieve the stress on the air bags? They loose air over about four or five days by them selves. Is that rate acceptable for air loss? Also what about dropping the hydrolic jacks when parked in storage

    I think your losing air over 4-5 days is acceptable.

    Concerning using jacks while stored. I've seen arguments/discussions both ways on this. Personally I just park the M/H and don't utilize the jacks. I do park the tires on a breathable rubber materia/mat I bought at HDl and cover the tires also. I take the M/H for a drive about once a month while in storage get the engine and transmission up to temp. Also exercise the generator with a load on it for about 1 hour every month.
