Proper Class C Storage

THANK YOU ALL for the wonderful information! It is much appreciated! I'm sure we will have more questions in the future...Blessings to you all!!!

For your fuel, put some Marine grade Stable in it. The Marine grade is the concentrate and much stronger than the red Stable.

Your RV has alarms and appliance controls that draw current while your rig is parked, disconnected from "shore power" . You need to disconnect the "house" battery(s) using the auxiliary battery switch or physically disconnect the negative battery cable to prevent the battery from becoming discharged fairly quickly. House battery(s) will self-discharge in a few weeks even while disconnected. A "smart" trickle charger should be connected to keep the house batteries charged but no over-charged. Overcharging shortens life of batteries. It is wise to check level of electrolytes monthly and replenish with DISTILLED water using a "turkey baster" type battery filler if house battery is connected and aux batter switch is on and rig is connected to 110volt "shore" power. Letting electrolyte levels go below the battery "plates" will damage the battery(s)House batteries last around 4 years if maintained properly. A generator expert told me to run the RV generator with roof AC on for two hours per month to keep the generator and it's fuel system working properly. I just spent nearly $800 on new house batteries and extensive RV generator fuel supply system work. The engine starting batter requires similar care and maybe a smart trickle charger to keep it charged but not overcharged. Keep the tires covered when parked for long periods. The fridge should be as level as practical when running and rig is parked . Running off level in the driveway will shorten the life of the fridge. The water heater and fresh water system also require maintenances. RV ownership requires knowledge and periodic maintenance activity much like owning a cabin cruiser or an airplane. There are some good You Tube videos on RV maintenance and repairs.

I store my rig with full gas tank - adding fuel stabilizer and running the generator b4 storing is good idea. I keep my rig plugged in during storage - my converter is "smart" so it keeps the coach batteries charged without damaging - I also added an inexpensive Trik L Start which insures my chassis battery is kept charged. I don't disconnect my batteries. I turn my fridge off (why waste electricity) but do keep the doors slightly open to avoid mold issue. Air conditioner isn't required in my area but I do use a small dehumidifier. My rig sits level on gravel - no leveling jacks.

Hi Happyheart,

I practice this for indoor storage. I would suggest the same for your RV port.

Full gas tank for sure. I would use a stabilizer only if storing the rig for significantly more than one calendar year. I don't feel the generator requires special care though other replies say otherwise.

I recommend to disconnect all batteries and charge them once every 4 months using a secondary charger.

Do NOT have active electricity operating through your rig's wiring during your storage period. Not 110V, not 12V. Keep everything shut down dead. You never know what can happen. RVs do catch fire once in a great while from a failed electrical appliance or function, or even rodent damage. Why take that risk unnecessarily?

Being in humid Texas, buy a large room dehumidifier and power it through an external 14 gauge power cord directly from your main house. Do NOT power it through the RV wiring. Setup the dehumidifier with a constant drain to the outside, set it so it feels comfortably dry inside, ideally at a setting that has the unit cycle on/off.

I would put 75 PSI in all the tires and park them on a hard surface. If parking on gravel or dirt, get 4 large 2x2 foot patio blocks and set the tires on them. You want water to drain off the blocks to avoid having the tires sitting in water.

Cover the tires from direct sunlight.

Do NOT extend your leveling jacks for so long of a period. A rusty film forming on the tubes will create retraction issues.

1. Is it ok to store with gas in tank with a gas stabilizer? If yes, does it matter how much gas?
yes, I put stabil in at last fuel stop prior to arriving home, run generator for at least 30 mins (even while on road) with AC on. stabil says good for up to 6 months.

2. Should it be kept plugged in to the 30amp electrical outlet?, your call, winnebago says NO in their manual to keep from overcharging coach battery (s). I put maint free ones in mine and keep it plugged in. You could disconnect and put a maintainer on them. I use 3amp maintainer on mine sometimes and always on my diesel truck batterys.

3. Should batteries be disconnected? (with or without electrical supply), see #2, I do put a maintainer on the chassis battery, leave connected.

4. Should refrigerator be stored on? (Therefore needing electrical supply).
Its your call no need to, just turn on a couple of days prior to use. Put box of baking soda in refer and freezer to keep smell down. Or you can put some ground coffee in a sock and put them in instead.

5. Should air conditioner be left on? (electrical supply)
Again your call, maybe if in hot humid area such as the south. If dry and hot 5 gal bucket of water is recommended we used to put 2 in when stored outside (have storage shed now). Need to monitor and refill about 1x a month. Supposed to keep wood work from warping/drying out.

6. Is it important for it to be stored level? If yes, tires only or leveling jacks too?
Issue if refer is left on and out of level. I leave on tires with plastic bed liner material under them. But mine is on concrete, but even if on dirt it would be beneficial. Also cover them. Check your manual on leaving the levelers down. Some say yes others no due to possible contaminants becoming lodged on the shafts.

Again, thank you!!!
