What to do when RV has been idle for more than a year

My 33ft Allegro motorcoach has been sitting idle in a storage facility for more than a year. I have been over and checked on the coach but I have not attempted to start the engine or the generator.
I would like to get my motorcoach operational again but I'm not sure what I need to do; I know I have to put air in the tires; should I put new fluids in the engine?
I would greatly appreciate any advice.

Thanks,

Michael

    Would agree -

    12 months is really not that long - Fuel treat is critical IMHO,- but everything else should be fine.

    I once bought a couple of 1961 B-61 Mack's - when they parked them they had a load of topsoil in the dump bed - we had to use a chainsaw to cut down the 6" tree growing in the back - added batteries, and air to the tires - drained fuel and started it up and drove it to the job - Had been parked for over 10 years, sold it 10 years later never missed a day.

    While it may have been better to run it, it will likely not be an issue.

    BOL,

  • Brake fluid is very important!

    Of course check your tires for the year they where manufactured. It will have a 4 digit number giving the week and year they where made. If over 7 years old, they might be more likely to have a blowout when driving over 60MPH. Yes I know the rules really well, but still drove my motorhome with some really old tires all the way from San Diego to Portland OR when the tires where about 11 years old. I kept it slow, at 55 to save gas.

    Good luck,

    Fred.
  • Here's how I'd approach it:
    1. Check the battery and recharge/replace as needed.
    2. Top off any automotive fluids before starting.
    3. Air up and inspect the tires.
    4. Take it to a reputable place and have oil, filter, trans fluid, trans filter, fuel filter, brake fluid and power steering fluid changed. Condensation over time can contaminate these fluids.
    5. Drain, fill, sanitize, drain and fill the fresh water tank and system.
    6. Go to an RV park or other place with full hook ups and check out all the RV systems just as you would during a predelivery inspection. Pay close inspection to the roof, including all caulking and seals around vents and other roof penetrations.

    Once everything checks out, hit the road and enjoy.
