How to Winterize an RV in Montrose: Motorhome Engine, Generator and Plumbing Checklist

MONTROSE RV WINTERIZING GUIDE
⏱ 4 min read · 📄 #876 words
A motorhome has more to winterize than a towable: an engine, a chassis battery, a generator and fuel on top of the plumbing. Here is a Montrose checklist for the whole rig, plus how to choose covered, gravel or pull-through storage across our Montrose locations.

I f you are putting a motorhome away for a Montrose winter, the simple answer is: winterize the plumbing, stabilize the fuel, exercise and then shut down the generator, disconnect or charge both battery banks, and protect the tires before it sits. A motorized RV has an engine and a generator that a travel trailer does not, and both need attention before a cold season. Montrose Self Storage has RV storage across Montrose, including covered parking, gravel parking and large drive-up units. Call (970) 249-5511 or compare our Montrose locations.

Why motorhomes need a longer checklist

Montrose winters are milder than the high country around it, but nights still drop well below freezing, and a rig can sit for months. A towable mostly needs its plumbing protected. A motorhome also has an engine, transmission, chassis battery, generator and fuel system, and each one can cause trouble in spring if it is put away carelessly.

Motorhome winterizing checklist

Fuel and stabilizer
Fill the tank most of the way to limit condensation, add a fuel stabilizer, then drive or idle so treated fuel reaches the engine.
Generator
Run the generator under load for a while after adding stabilizer, then shut it down. Follow your generator manual for storage.
Engine fluids
Check antifreeze strength and top off fluids. Consider an oil change before storage so used oil does not sit all winter.
Two battery banks
Charge the house and chassis batteries fully, then use the disconnect or remove them and keep them on a charger.
Plumbing
Drain all tanks and lines, bypass the water heater, then add RV antifreeze to lines and traps or blow them out with air.
Tires and seals
Set tire pressure, use tire covers against sun, and check roof and slide seals before winter weather.

Choosing RV storage across Montrose

Covered parking

Our 9th Street and Fruit Park locations have covered parking with an overhang that keeps sun, hail and most snow off the roof. Covered spaces are popular, so check availability early.

Gravel and open parking

9th Street also has gravel parking, Fruit Park has open parking up to 10x40, and Spring Creek has 10x30 open parking. These suit a well winterized rig and a tighter budget.

Drive-up units

For a smaller motorhome or a rig you want behind a door, 9th Street has drive-up units up to a 12x40 pull-through. Fruit Park also has large drive-up and shop units.

Not sure which fits? Read our guide to covered vs uncovered RV storage in Montrose, or call (970) 249-5511 with your rig length.

Before you drive away

Close blinds to reduce sun damage, remove food, leave the fridge door propped open, and set rodent deterrents. Turn off the propane, and leave a copy of the winterizing list on the dash so you know where to start in spring. Storing a hunting trailer or ATVs as well? See our trailer and ATV storage guide.
