Storing a fifth-wheel trailer and a motorhome may look similar on the surface, but the differences in their design, weight, and access points require distinct approaches. The key factors to consider are height clearance, weight distribution, seasonal preparation for slides and roofs, and the unique vulnerabilities of each type. Below is a practical comparison to guide your storage decisions.
Height and clearance considerations
A fifth-wheel trailer typically has a raised front section that sits over the truck bed, which can make the overall height taller than a comparable motorhome. Many fifth-wheels exceed 13 feet in height, while Class A motorhomes often range from 11 to 13 feet, and Class C models are usually under 11 feet. Before committing to a storage unit, measure your rig’s maximum height with all antennas, air conditioners, and satellite dishes in their highest position. A storage facility with a clearance of 14 feet or more is best for tall fifth-wheels, whereas motorhomes may fit under 12-foot clearance. Always confirm the clearance with the facility manager before moving in.
Weight-bearing and floor structure
Fifth-wheel trailers place heavy loads on the kingpin and the rear axles, which means the storage surface must be smooth and level to avoid stress on the frame. Motorhomes have their weight distributed across the chassis, making them less sensitive to minor grade changes, but both types benefit from a paved or gravel surface. For long-term storage, consider placing jack stands or leveling blocks under the fifth-wheel’s landing gear to prevent settling. Motorhomes should be parked on level ground with the parking brake engaged, but they do not require additional supports unless the storage facility recommends them.
Slide-out preparation
Both fifth-wheels and motorhomes have slide-out rooms, but the mechanisms differ. Fifth-wheel slides often extend farther and may have more moving parts, so it is vital to retract them fully before storage, especially if the facility is uncovered. Moisture and debris can damage seals. Motorhome slides are generally easier to retract and lock, but still need to be fully closed and secured. If storing indoors, you may extend slides for ventilation, but only if the facility allows it and the unit is level. Always check the slide seals for wear before storage; replace any cracked seals to prevent leaks.
Motorhome-specific storage needs
Motorhomes have engines, batteries, and fuel systems that require attention during storage. Run the generator under load for at least 30 minutes before storing to circulate fuel and stabilize the system. Fill the fuel tank to prevent condensation, add a fuel stabilizer, and disconnect the chassis battery or use a trickle charger. Motorhomes also have house batteries; disconnect them or maintain them with a solar panel or shore power connection if available. In cold climates, drain the fresh water and gray/black tanks, and add RV antifreeze to the plumbing system. Never rely on the storage facility’s power for battery maintenance unless you have written permission and a plan to monitor them.
Fifth-wheel trailer storage specifics
Fifth-wheel trailers have no engine, so the storage focus is on the suspension, tires, and exterior. Inflate tires to the manufacturer’s recommended pressure before storage, and consider using tire covers to protect from UV rays. The kingpin and landing gear should be lubricated to prevent rust. For winter storage, drain all water lines, the water heater, and the fresh water tank. Use RV antifreeze in the plumbing. The roof is a common weak point on fifth-wheels because they tend to have more laps and seams. Inspect the roof membrane and seal all seams with approved sealant before storing. If storing outdoors, cover the roof with a breathable tarp designed for RVs.
Security and access differences
Motorhomes are drivable, so they are often easier to move quickly if needed, but they can be a target for theft due to their drivetrain. Fifth-wheel trailers are less likely to be stolen without a truck, but their jacks and hitch can still be tampered with. Regardless of type, choose a storage facility with perimeter fencing, 24/7 video surveillance, and individually gated entrances. For motorhomes, consider removing the steering wheel lock or installing a hidden kill switch. For fifth-wheels, use a coupler lock on the kingpin and locking lug nuts on the wheels. Ask the facility if they allow periodic access for starting the engine or moving the unit; many do, but some charge extra.
Climate considerations for each type
In hot and humid climates, both types face mold and mildew, but fifth-wheels with vinyl roofs can develop blisters from heat. Motorhomes with rubber roofs are more resilient but still need shade or a cover. Indoor storage with climate control is ideal for preserving upholstery, electronics, and appliances in both. In cold climates, motorhomes need a block heater or engine warmer if stored outdoors for long periods. Fifth-wheels have no engine, so they require only plumbing winterization and tire protection. Gravel or asphalt outdoor storage is acceptable for milder climates, but always use tire covers and place the unit on level ground to avoid frame twist.
Choosing the right storage facility
When comparing storage facilities, look for one that can accommodate the specific height and weight of your rig. For fifth-wheels, verify that the gate clearance is at least 14 feet and that the driveway has no sharp turns. For motorhomes, ensure that the turns are wide enough for a Class A. Ask about current occupancy rates and if they have waitlists. Reputable facilities will provide a written contract detailing access hours, fees, and liability. Read all terms carefully, especially regarding what happens if the unit is damaged by weather or vandalism. Do not assume the facility’s insurance covers your possessions; confirm with your own insurer what coverage applies while the rig is in storage. This answer is general guidance only. Local ordinances, lease terms, and insurance policies vary. Confirm rules and limitations with the storage facility, your municipality, and your insurance provider before making any storage decisions.
