Choosing the right refrigerated trailer shouldn’t feel like guesswork. Whether you’re storing food, beverages, flowers, medical supplies, or event inventory, the size you choose directly affects how smooth your day goes. This guide breaks down the different trailer sizes Refrig-A-Rent offers, what you can realistically fit inside each one, and the types of jobs they’re best for.

Below is a clear comparison to help you make the right call the first time.

Small Refrigerated Trailer (6–8 ft)

Best for: smaller events, light food storage, beverage cooling, small businesses, mobile bartending, and short-term pop-ups.

What Fits Inside a Small Unit

A small refrigerated trailer is compact, efficient, and easy to maneuver. Inside, you can typically fit:small-walk-in-cooler-for-rent

25–35 full-size catering trays

  • 30–40 cases of beverages

  • 4–6 standard restaurant food pans per shelf

  • 2–3 rolling racks (bakery height)

  • Small floral orders or bouquets

  • Limited medical supplies and specimen coolers

Best Use Cases

This size works great for:

  • Backyard weddings

  • Graduation parties

  • Small caterers

  • Pop-up food vendors

  • Farmers market booths

  • Breweries needing a little overflow

  • Convenience stores waiting on cooler repairs

If you don’t need walk-in space and just want a mobile cooler to keep things chilled, this size is perfect.

Medium Refrigerated Trailer (10–12 ft)

Best for: restaurants during walk-in outages, multi-day events, festivals, mid-size catering operations, florists, and product distributors.

What Fits Inside a Medium Unit

This is the “sweet spot” size — walk-in convenience without going too big. You can typically fit:medium-refrigerated-trailer-for-rent

  • 60–80 catering trays

  • 65–85 cases of beverages

  • 4–6 metro racks (full height)

  • Half a pallet of boxed product

  • Bulk produce cases (apples, lettuce, tomatoes, citrus, etc.)

  • Large floral orders or holiday overflow

Because this trailer is walk-in accessible, you can organize product like you would inside a commercial kitchen cooler.

Best Use Cases

Choose a 10–12 ft trailer for:

  • Restaurants during busy season or equipment failure

  • Medium to large catering events

  • Breweries preparing for festivals or can releases

  • Small grocery stores handling holiday overflow

  • Florists needing temporary cooler space

  • Medical, lab, or chemical storage with controlled temperatures

If you need space you can walk into — but not the full warehouse-style setup — this is the most flexible size.

Large 16-ft Walk-In Refrigerated Trailer

Best for: large events, farms, grocery stores, medical groups, distributors, and any business that needs the maximum possible walk-in cold storage.

What Fits Inside a Large 16-ft Walk-In

This is your big-capacity, heavy-duty unit. Expect to fit:large-walk-in-cooler-for-rent

  • 120–160 catering trays

  • 120+ cases of beverages

  • 8–12 full-height metro racks

  • 1 full pallet of product or two half pallets

  • Large quantities of produce, dairy, proteins, or frozen goods

  • Full-scale floral holiday inventory

  • Bulk medical or pharmaceutical shipments

This size is ideal when you need true walk-in cold storage with room to move, sort, and store inventory like you would inside a commercial cooler.

Best Use Cases

Our 16-ft walk-in trailer is the right choice for:

  • Large catering companies delivering multiple events

  • Grocery stores managing holiday overflow or equipment outages

  • Farms storing produce, meat, or CSA boxes

  • Breweries distributing kegs or preparing for festivals

  • Medical groups transporting vaccines, samples, or temperature-sensitive chemicals

  • Emergency refrigeration during major breakdowns

  • Event venues hosting multi-day festivals or athletic events

If you want maximum space, steady temperatures between 0° and 50°F, and the ability to treat it like a full walk-in cooler, this is the top pick.
