A trailer includes at least a plurality of fabric support connections that retain a plurality of fabrics spaced apart from one another so as, if desired, to insulate the roof and side walls of the trailer. In one embodiment, the plurality of fabric support connections are connected by way of extrusions to some of the sides of the trailer and further provide insulation by forming a double wall on those sides. In another embodiment, the plurality of fabric support connections form a double wall only on certain portions of the top side of the trailer.

A pallet is provided for supporting cylinders. The pallet can have a convex spine extending substantially the length of the pallet in a longitudinal direction, having a backstop at a first end. The pallet has one or more trays attached transverse to the convex spine, each tray having longitudinal fluted indents to restrain a cylinder from rolling transverse, the longitudinal fluted indents are each arranged to accept a cylinder from above. The pallet has a left outrigger attached and extending transverse to the convex spine, the left outrigger stabilizing the pallet with respect to terrain, as well as a right outrigger attached and extending transverse to the convex spine, the right outrigger stabilizing the pallet with respect to terrain. The pallet can have a coupling extending from an end of the convex spine, wherein the coupling is arranged to take a crane hook in engagement to pull the pallet.

Quick-release skis couple to the front wheels of an ATV or other wheeled vehicle, to permit the ATV to travel over snow. The rear ATV wheels may be left unaltered, or more commonly, tracks may be substituted for the rear wheels. The ski coupling includes a drive-on runner and coupling having in one embodiment width-adjustable side walls, an over-center clamp, and a lock for securing the over-center clamp. In a second embodiment, a pivotal tire cage allows the ATV tire to be driven onto the ski, but simply by forward travel of the tire the cage pivots to constrain the tire thereon. A strap then binds the tire and cage to ensure the tire stays in place on the ski. In a third embodiment, an ATV track is converted to a runner by the application and tensioning of a ski. Additional embodiments are illustrated.

A cooler sled device for facilitating transport of a cooler over surfaces such as gravel, loose terrain, and sand includes a panel. A bottom surface of the panel is convexly curved between outer sides of a perimeter edge of the panel and extending rearwardly from a front side of the perimeter edge defining an upwardly turned front section of the bottom surface. Each of a pair of wells is positioned on an upper surface of the panel and proximate a respective one of the outer sides of the perimeter edge for receiving wheels coupled to a cooler positioned on the panel. A strap is positionable to extends across the upper surface of the panel for securing the cooler on the panel.

A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

A devise that makes it possible to use common-or-garden wheelbarrow in snow or other slippery conditions. The device can be used on any standard wheelbarrow and deployed in a matter of a few seconds, without any disassembly or adjustment to the wheelbarrow. The device consists of aplastic board, similar to a children's training snowboard, approximately 104 cm (41 inches) long and 28 cm (11 inches) wide, to which a metal cradle is attached in the center to snugly hold the wheel of the wheelbarrow.
