Polar King Mobile (PKM), the leading provider of affordable refrigerated and freezer trailers, announces Central Trailer Sales is the newest dealer to join the company’s growing nationwide network.
With two locations in Greater Minneapolis and St. Paul, Central Trailer Sales has offered a variety of trailer sales for more than two decades. Now, the business will offer mobile refrigeration for the first time.

Brian Renstrom, owner of Central Trailer Sales, says, after researching the marketplace, PKM offers the best refrigerated and freezer trailers. “This partnership allows us to offer an innovative solution that meets real-world needs in industries that often go overlooked. By adding Polar King Mobile, we’re now able to better serve niche and often underserved markets like disaster relief, catering, floristry, and more by helping our customers go further with the right tools for the job.”
Polar King Mobile offers refrigerated and freezer trailers designed specifically for outdoor, over-the-road use. Manufactured in the Midwest, these all-electric trailers feature a seamless fiberglass interior and exterior for the best insulation for cold storage purposes.
Tailored to meet the needs of every cold storage industry, PKM has helped numerous businesses in the foodservice, catering, education, hunting, and agricultural industries, as well as artisan businesses.
Polar King Mobile currently offers three standardized trailer sizes: 6’x8’, 6’x12’ and 6’x16’. Recently, the company announced its Avalanche Series, which offers drop-deck refrigeration.
