How to Prepare Your RV or Boat for Storage in Medicine Hat
Alberta winters are no joke — and nothing shortens the life of an RV or boat faster than going into storage unprepared. A few hours of proper prep in the fall can save you thousands in repairs come spring.
This guide covers everything you need to do before dropping your recreational vehicle off at Railside Storage.
RV & Camper Prep Checklist
1. Winterize the Water System
This is the most critical step. Water left in pipes will freeze, expand, and crack your lines.
- Drain all fresh water tanks completely
- Flush the water heater and drain it (turn off the heater at least 24 hours in advance)
- Blow out all water lines with compressed air or use RV antifreeze
- Leave faucets slightly open so any residual moisture can escape
- Drain the toilet and pour a small amount of RV antifreeze into the bowl
2. Clean the Interior Thoroughly
Pests are drawn to food residue — and they'll find anything you leave behind.
- Remove all food, including canned goods and sealed packages
- Clean out the fridge and freezer; prop the doors slightly open to prevent mold
- Wipe down all surfaces
- Vacuum floors and upholstery
- Leave a few dryer sheets or cedar blocks to deter rodents
3. Protect the Exterior
- Wash and wax the exterior before storing — dirt and moisture trapped against the finish cause long-term damage
- Inspect and seal any roof seams, window edges, or door seals that look cracked
- Cover roof vents with mesh to prevent insects and mice from entering
- Consider a quality RV cover if storing outdoors
4. Take Care of the Battery
- Fully charge the battery before storing
- If storing long-term, disconnect it or use a trickle charger to prevent discharge
- Check electrolyte levels (if not sealed)
5. Tires and Wheels
- Inflate all tires to the recommended pressure — cold temperatures lower PSI
- If storing for more than 3 months, consider placing the RV on levelling blocks to take weight off the tires
- Check wheel chocks are secure before leaving
6. Fuel and Engine
- Add fuel stabilizer to the tank if storing for more than 30 days — prevents gumming in the fuel system
- Change the oil before storing if it's near due — old oil is acidic and can cause wear over winter
Boat Storage Prep Checklist
1. Flush the Engine
Salt and mineral buildup damages engine internals. Flush with fresh water immediately after the last use and again before storage.
2. Fog the Engine
Spray fogging oil into carburetors and cylinders to prevent corrosion during storage.
3. Change the Engine Oil
Store with fresh oil — old oil contains combustion acids that corrode engine parts over months of sitting.
4. Drain All Water
- Drain the bilge completely
- Remove the drain plug and store it inside the boat
- Drain any live wells or bait tanks
- Flush and dry the ballast system (if applicable)
5. Clean and Wax the Hull
Remove algae, waterline stains, and oxidation before storing. Apply a coat of wax to protect the gelcoat over winter.
6. Remove Electronics and Valuables
Electronics deteriorate in cold storage. Wherever possible, remove fish finders, GPS units, stereos, and anything valuable from the boat before storing.
7. Cover It Properly
A well-fitted cover keeps moisture, debris, and pests out. Shrink-wrap is the gold standard for long-term outdoor storage — it's watertight and won't flap in the wind all winter.
Outdoor vs. Indoor Storage for Your RV or Boat
Most recreational vehicles are stored outdoors in a gated lot — which works well when the vehicle is properly prepped and covered. Outdoor storage is more cost-effective and handles larger units with ease.
If you have high-value items inside your RV or boat, or if you're storing smaller trailers and personal watercraft, indoor storage units at Railside provide additional protection from temperature extremes and weather.
