The lakes and rivers around the Twin Cities metro make Minnesota one of the best places in the country to own a boat or RV. But the long winters mean most recreational vehicles spend a good chunk of the year in storage — and how you prepare them before that storage period makes a big difference in how they come out in the spring.

The first step is a thorough cleaning, inside and out. Moisture and organic material left behind are the primary culprits behind mold, mildew, and deterioration during storage. Remove all food, wipe down interior surfaces, and flush any compartments where water or debris might collect.

Draining all fluid and water systems is equally important before the cold sets in. For boats, that includes the bilge, livewells, and any freshwater lines. For RVs, drain the fresh water tank, water heater, and holding tanks, then blow out the lines or add antifreeze rated for potable water systems. Skipping this step is one of the most expensive mistakes recreational vehicle owners make.

Battery care is another area worth attention. Cold temperatures drain batteries faster than most people expect. Disconnecting and storing the battery in a warmer environment — or keeping it on a quality trickle charger — will save you the frustration of a dead battery when you're ready to head out in May.

Tire health is easy to overlook when a vehicle is just sitting. Inflate tires to the manufacturer's recommended pressure before storage, and if possible, move the vehicle a few feet every month or two to prevent flat spots from developing on the contact points.

Finally, a good breathable cover goes a long way. It protects against UV exposure, bird droppings, and weather — while still allowing airflow to prevent moisture buildup underneath. For boats stored outdoors, a properly fitted cover can add years to the life of your upholstery and hull finish.

Outdoor RV and boat storage facilities in the southeast metro area — including options in Hastings near the St. Croix and Mississippi confluence — offer convenient, accessible options for owners who don't have room at home. Look for facilities with easy pull-through access and good visibility from the road, which typically indicates an active, well-maintained operation.
