A trailer includes a set of removable castor wheels attached to a rear portion thereof, wherein the castor wheels are oriented to face rearwardly when the trailer is oriented in the traditional horizontal position. This arrangement allows the trailer to be tilted upwardly into a vertical orientation so that it rests on the castor wheels, thus providing an apparatus and method for easily moving and storing trailers more efficiently due to the reduced footprint required for such trailer storage. The castor wheels, in one embodiment, include mounting brackets that may be attached to the trailer using a securing rod, similarly to the mounting mechanisms commonly used for removably attaching trailer hitches into trailer hitch sleeves, thus rendering the castor wheels removable from the trailer when they are not in use for storage purposes.

A trailer system with a modular design is provided for the transport of tiny homes. The system comprises a front hitch assembly to connect to a suitable towing or transport vehicle, and a rear axle assembly designed to carry the weight of a tiny home. The trailer bed portion of the trailer system is the tiny house foundation adapted to connect with the front hitch and rear axle assemblies in a lowboy configuration. Each of the front hitch and rear axle assemblies have pegs that can be secured into channels formed into the end walls (e.g. slots/cavities) or alongside walls (e.g. grooves) of the foundation. Once inserted into the channels, the pegs can be secured to the foundation using a securing means (e.g. locking pins). After transport of the tiny home, the front hitch and rear axle assemblies can be connected to each for transport to another location.

A spatial integration module includes a chassis, a wall body, a top cover and supporting devices. Each supporting device comprises a lower fixed portion and an upper movable portion. The wall body is detachably connected to the chassis and/or the supporting devices. The fixed portions are mounted on the chassis. A fixed rotation structure is arranged at a position where each movable portion is connected to the corresponding fixed portion. Each movable portion is turned between a horizontal direction state and a vertical direction state by the rotation structure.

In the case of a travel trailer having a battery and an axle (13) or a tandem axle, the battery (9) is designed for supplying electricity to a travel drive of a towing vehicle and/or to an optional travel drive of the travel trailer during trailer travel in road traffic, and is arranged as a flat battery (9) below a floor of the travel trailer, in a vehicle frame (1), wherein the height of the battery (9) essentially corresponds to the height of the vehicle frame (1).

A trailer is disclosed which includes a first door with a first hinge configured to allow the first door to operate between an open position and a closed position, and a second door on the opposing side of the trailer with a second hinge configured to allow the second door to operate between an open position and a closed position. The trailer also includes a roof and a trailer tongue with a coupling configured to attach to a hitch of a vehicle. Two or more wheels are provided that are extendable from an up position to a down position. In this way, when the wheels are in the down position, the trailer is lifted off the ground. The trailer can thus change between at least three modes, including a first mode for storage, wherein the first door and second door are in the closed position and the wheels are in the up position; a second mode for ingress and egress, wherein at least one of the first door and second door are in the open position; and a third mode for travel, wherein the first door and second door are in the closed position and the wheels are in the down position.

A trailer frame is disclosed that comprises a panel with a plurality of inserts installed at certain hard point locations where external components and equipment may be attached. In one embodiment, the inserts are two-piece formed hard points, whereas in other embodiments, the inserts are one piece solid hard points. In some embodiments, the panel is a sandwich panel. The inserts may be installed in the panel in a variety of manners, for example, they may be set flush within shallow pockets machined or routed into the panel's outer skins. Also, brackets may be utilized to interconnect components or equipment to the hard point inserts.

A holiday trailer may comprise a removable stand for rotating the trailer from a horizontal position to a vertical position for storing the trailer. The trailer may house a tent which is extendable in a longitudinal direction away from a body of the trailer. The trailer may comprise a work surface which is removably attached to the trailer.

An air ride trailer floor and method to provide shock isolation for cargo of a trailer, A plurality of air bags are preferably provided and are attached atop or above a trailer frame and one or more air ride floors are attached to a top of the plurality of air bags such that cargo which rests on the one or more air ride floors receive not only shock isolation from a road surface due to the conventional suspension system of the trailer (if any), but also receive additional shock isolation through the air ride floor. The stiffness of the isolation of the air ride floor can be adjusted by adjusting pressure of gas within the plurality of air bags.

The invention discloses a mobile pellet fueled variable frequency barbecue oven as well as an electric cabinet assembly and a control circuit thereof, and relates to the field of vehicle-mounted barbecue ovens. The mobile pellet fueled variable frequency barbecue oven includes a chassis assembly, wherein the chassis assembly is connected with an automobile; a cabinet arranged above the chassis assembly, wherein the cabinet consists of a lower cabinet and a fuel tank assembly which are arranged oppositely, and is provided with a barbecue oven cavity for accommodating a food grate; and an electric cabinet assembly, wherein both sides of the electric cabinet assembly are electrically connected with the cabinet and the automobile power supply respectively to provide working power for the barbecue oven and control stable power supply of the barbecue oven. The mobile pellet fueled variable frequency barbecue oven as well as the electric cabinet assembly and the control circuit thereof replace a power supply assembly and a circuit of a traditional vehicle-mounted electric barbecue oven through a low voltage actuator, thus realizing low power operation of the vehicle-mounted barbecue oven, realizing normal work during movement of the vehicle, broadening the applicable scenarios of the vehicle-mounted barbecue oven, and being more suitable for actual use requirements.
