Berry converted the engine from gas to propane so the whole thing runs off of one tank .

Steve Berry’s hot dog stand doesn’t look like anyone else’s.

Sure it has the red and yellow umbrella and the telltale tufts of steam, but that’s where the similarities end.

Berry bought an old Cushman truck, cut out the back and then had a special unit designed to fit in the truck’s bed. It took a year and half of tinkering and $12,000, but it was worth the effort.

The self-contained unit has seven steamer bins to keep foods hot and to provide hot water for washing utensils, as well as a cooler for sodas and a refrigeration unit to keep condiments cold. A pantry holds spoons, napkins and other utensils. A collapsible shelf on the passenger door gives customers a spot to dress their dogs.

He also modified the cab for storage so he can carry more than 100 sodas and 100 dogs and buns on any given day. There’s just enough room behind the steering wheel for the driver.

Berry also converted the engine from gas to propane so the whole thing is powered by one tank of propane gas. The diminutive truck can take him wherever he needs to go.

For now, Berry plans to stay at his Lincoln Street location, thanks in part to F.X. Marcotte owner Paul Bonneau’s good will. Bonneau is letting Berry park Top Dog on property across the street from the furniture store free of charge.

Berry is there from 11 a.m. to 1 p.m. Monday through Friday.
