• Trail-Ur-Boat for "the sportsman"
• Utility Trailer with permanent Duralumin top
• Utility Trailer with removable steel top

In the sportsman configuration, the 300 pound trailer included a 100 Duralumin boat that served as the trailer's "top" or "cover." The bottom half (top drawing on left) had room for a "three-quarter wide, full length mattress and springs, stove, provisions and a small outboard motor."

In case of "inclement weather the boat is raised on stanchions provided and the storm curtain is buttoned around it affording protection to the occupants."
Company literature said the "utility" version with permanent top (middle & bottom drawing on left) was offered as a model to be used by "regional service men who must carry a stock of replacement parts and tools." The drawings show the permanent top (middle drawing on left) to be the skin of Duralumin boat fixed permanently to solid sides containing windows.

The company said the other "utility" version (the bottom half of the Trail-Ur-Boat with an optional top made of "body steel") made a "graceful utility trailer without par" and was "invaluable wherever transportation of small articles is required."
