Abstract: An undercarriage sprayer includes a plurality of nozzle blocks aligned side-by-side, where each of the nozzle blocks includes a lateral channel therethrough and an upward-facing nozzle cap. A conduit extends between each of the lateral channels in fluid communication with each of the nozzle caps. The nozzle blocks prevent the water supply from being crushed when driving a vehicle over the undercarriage sprayer. Additionally, the nozzle blocks may be connected such that the undercarriage sprayer can be folded or rolled on itself.

Abstract: A double rafter for vehicle roof system including a rafter having a top arcuate-member, a base-member, and a plurality of support members. The top arcuate-member is positioned on top of the base-member in a stacked series extending along a length of the base-member when installed. The plurality of support members are disposed between and create a gap between the top arcuate-member and the base-member. The top arcuate-member is supported via the plurality of support members in a partially elevated and contoured position above the base-member. The top arcuate-member comprises a contoured profile to contour to and support an underside of a vehicle roof. The device may be used for installation of a recreational vehicle roof. Further, the device may be used to prevent offset seams in ceiling panels.
