The base has a length and a width. The plurality of side walls are connected to the base, and extend generally normal to the base. The plurality of side walls include opposing side wall portions and opposing end wall portions. The crossbar is supported by the opposing end wall portions, and is positioned intermediate the opposing side wall portions. The seat is supported by the crossbar and a first one of the opposing side wall portions. Further disclosed is a method of connecting a wear strip to a sled.

[0017] While some of the above-identified figures set forth one or more embodiments of the invention, other embodiments are also contemplated, as noted in the discussion. In all cases, this disclosure presents the invention by way of representation and not limitation. It should be understood that numerous other modifications and embodiments can be devised by those skilled in the art, which fall within the scope and spirit of the principles of the invention. DETAILED DESCRIPTION [0018] The present invention relates to a portable shelter sled. The sled includes a base, a plurality of side walls, and a seat supported between one of the side walls and a crossbar resting on opposite end walls of the sled. The use of a crossbar to support a seat improves user access to supplies and equipment carried in the sled. The sled can also carry a pivoting frame/canopy system for providing a shelter that incorporates the sled. [0019] FIG. 1 is a perspective view of an embodiment of a portable shelter sled 20. Sled 20 is formed of a polymer, such as high density polyethylene, in a molding process, and generally comprises a base 22 and a plurality of interconnected walls 24 and 26, which are configured at an upper extent with a perimeter ledge 28. Walls 24, 26 are dimensioned to define a pair of opposing side walls 24A and 24B and a pair of opposing end walls 26A and 26B, with side walls 24A and 24B having a greater length than end walls 26A and 26B. Base 22 is rounded at opposite ends 30A and 30B to permit sled 20 to be towed or pulled from either end 30A or 30B, such as with the aid of a tow rope 32 or other suitable towing connector. Sled 20 may also be equipped with a pivoting frame/canopy system 34 (shown in phantom) conventional in the art of sled-mounted portable ice fishing shelters. [0020] Unique to the portable shelter sled 20 of the present invention is the addition of a crossbar 36 mounted to the ledge 28 of opposing end walls 26A and 26B. In one embodiment, crossbar 36 is generally medially positioned relative to opposing side walls 24A and 24B. Crossbar 36 serves as a support for mounting one or more seat assemblies 38 on sled 20. As shown in FIG. 1, seat assemblies 38 generally comprise a frame or bridge assembly 40 having a first mounting bracket 42 supported by a portion of ledge 28 associated with side wall 24A and a second mounting bracket (not shown) supported by the crossbar 36. The incorporation of crossbar 36 on sled 20 creates an unobstructed space 44 between crossbar 36 and side wall 24B to allow easy access to ice fishing gear and supplies stowed in sled 20.
