If you’ve been in the ice cream truck body supply game for long, you know the off-season isn’t just a slow period—it’s a make-or-break window to protect the custom truck bodies you’ve built for vendors across the country. Last winter, we had a customer reach out to us panicking because the fiberglass exterior of their stored ice cream truck body had developed hazy, water-stained spots, and the insulated panels inside had grown faint mold patches. They’d parked it in a rented warehouse bay and checked on it once a month, but they’d skipped a few key steps. That’s what made us realize: most first-time ice cream truck operators (and even some repeat vendors) don’t understand that a truck body isn’t just a metal shell that can sit for months without intentional care. As a supplier that designs, fabricates, and ships 40+ custom ice cream truck bodies a year, we’ve refined our off-season storage process over 12 years of working with small business owners and regional fleets. Today, we’re breaking down the science-backed steps we recommend for storing your ice cream truck body during the off-season—no fancy equipment required, just consistent, intentional work that will save you thousands in repairs when warm weather rolls around. Ice Cream Truck Body
First, let’s talk about the pre-storage prep, because this is the part most people skip, and it’s the root of 80% of off-season damage. Your ice cream truck body has specific components that are designed to hold cold, but when left idle for months, they become breeding grounds for moisture, pests, and corrosion. Let’s start with the insulated cargo area—this is the core of the body, right? Most of our bodies use closed-cell polyurethane insulation, which is dense and moisture-resistant, but it’s not impermeable. Any crumbs, melted ice cream residue, or standing water left in the storage bins, door tracks, or under the floor panels will attract pests and feed mold over time. We always tell our customers to fully strip the body before storage: remove all sliding shelves, bin liners, and drip trays, and wash every surface with a mild, food-safe detergent (no bleach—bleach can eat away at the protective seal on fiberglass and metal over time). For hard-to-reach areas like the gaps around the refrigeration unit’s mounting points or the track under the rear service door, use a soft-bristled brush to scrub away buildup, then wipe dry completely with microfiber towels. A quick test we recommend: after cleaning, leave a dry paper towel in the cargo area for 24 hours. If it comes out damp, there’s a hidden leak or moisture buildup you need to fix before storing—even a small 12×12 inch damp spot can turn into 2 square feet of mold by spring.
Next, the refrigeration unit and plumbing lines—these are the most expensive components of the body, and they’re fragile when sitting unused. If you leave refrigerant lines connected and the unit powered off, condensation can form inside the compressor, leading to rust and a failed startup when you need it. Our team always advises customers to schedule a professional refrigeration service check two weeks before storing: this includes flushing any remaining water from the drain lines, tightening all electrical connections to prevent corrosion, and adding a protective coating to the compressor’s exposed metal parts. If you’re storing a body that doesn’t have a refrigeration unit mounted yet (some operators remove theirs during off-season to rent out their chassis), make sure to plug the refrigerant line ports with rubber caps to keep dirt and moisture out—this is a small step that saves hundreds on professional repairs later. We also recommend turning all plumbing valves to the “closed” position and leaving faucet handles slightly loose—this prevents pressure buildup if water freezes (even in unheated storage) and makes it easier to drain lines completely when you prep for the next season.
Now, the exterior and structural components. Ice cream truck bodies take a beating on the road: sun exposure, road salt, rain, and the constant opening and closing of doors. During storage, these elements are still a threat, just at a slower pace. Let’s start with the exterior paint and fiberglass—most of our bodies use a high-gloss UV-resistant paint, but that’s not a permanent shield. Before storing, wash the entire exterior with a non-abrasive car wash soap, and wax it with a polymer-based carnauba wax. This creates a barrier against dust, tree sap, and environmental pollutants that can etch into the finish over several months. For metal parts like door frames, hinge pins, and underbody braces, apply a thin coat of lithium-based grease—this prevents rust from forming in the small gaps where moisture can get trapped. If your storage space has overhead tree cover or is near construction, use a breathable, custom-fit truck body cover, not a plastic tarp. Plastic tarps trap moisture against the exterior, leading to mold and discoloration, while a breathable cover allows air to circulate, keeping the exterior dry. We sell custom covers for all the bodies we supply, and we’ve heard from customers that the $150 investment saves them $1,000+ in exterior repairs each off-season.
The storage space itself is just as important as the prep work. You can do everything right to the body, but if you park it in a damp, cluttered warehouse, you’ll still have issues. Here’s what we recommend for choosing a storage spot: first, it should be flat and level. If the body is sitting on an uneven surface for months, it can warp the underfloor insulation or bend door frames, making them hard to open later. Second, it should be dry—avoid spaces that have a history of standing water or high humidity (we recommend a space with less than 50% relative humidity; you can pick up a cheap hygrometer at a hardware store to test this). Third, it should be pest-free. Rodents and insects are a huge problem for stored truck bodies—they’ll chew through wiring, build nests in the insulation, and even get into the storage bins. To prevent this, don’t store any food or cleaning supplies in the same bay as the body, and place mothballs or rodent repellent pouches (safe for fiberglass and metal) in the corners of the cargo area, not directly on insulation or painted surfaces. If you’re storing the body outdoors (we only advise this for short-term off-season storage, like 2-3 months in mild climates), add extra steps: elevate the body on jack stands to keep it off the ground, use a heavy-duty cover with grommets for airflow, and check on it every two weeks to wipe down any collected dew or dirt.
Once the body is in storage, don’t just forget about it until spring. Consistent checks every 4-6 weeks will catch small issues before they become big problems. We tell our customers to do two quick checks: first, walk around the exterior to look for signs of water pooling under the cover or on the body, and check for any new rust spots on metal parts. Second, open the cargo door and check for any unusual smells (mold has a distinct earthy scent) or moisture buildup on the walls or floor. If you notice a damp spot, wipe it dry and adjust the cover’s airflow if needed—sometimes a cover that’s too loose can trap moisture, while a cover that’s too tight doesn’t let air circulate. Last winter, one of our fleet customers in Ohio noticed a small mold spot in the corner of their body during a mid-season check; they wiped it down with a vinegar-water solution (mild vinegar kills mold without damaging surfaces) and adjusted their storage bay’s dehumidifier, saving themselves a $800 professional mold remediation bill.
When spring rolls around, the prep isn’t over—there are a few final steps to make sure the body is ready for the road. First, remove the cover and let the body air out for 24 hours before starting any work. Then, do a full inspection: test all door mechanisms, check electrical connections, and run the refrigeration unit for 30 minutes to make sure it’s working properly. Remove any repellent pouches from the cargo area, wash the exterior again to remove dust and debris, and re-tighten any loose bolts. We always recommend scheduling a pre-season service check with a professional refrigeration technician a week before you plan to start your routes—this ensures the unit is working at peak efficiency, which is critical for keeping ice cream frozen during hot summer days.
As a supplier, we don’t just sell you a custom ice cream truck body—we’re here to support you through every step of owning and maintaining it, including off-season storage. We’ve seen vendors cut corners on storage and end up with bodies that can’t be used for weeks, missing out on early summer sales, and we’ve seen others follow these steps and get years of extra life out of their custom bodies. If you’re preparing your body for this off-season, or if you have questions about storage, maintenance, or custom ice cream truck body design, our team is here to help. We work with vendors of all sizes, from first-time operators with one small body to regional fleets with 20+ units, and we can provide personalized advice based on your specific body model and storage location. Don’t wait until warm weather is almost here to find out your body has damage—start the storage process now, and you’ll be ready to hit the road as soon as the ice cream craving hits.
