Vehicles, such as all terrain vehicles, can be provided with a frame and a fender assembly. The fender assembly can have layered fender panels attached together with a bolt and T-nut. A channel can be formed between the fender panels to facilitate passage of fluid along a predetermined pathway. A seat includes a compression surface for sandwiching the fender assembly with respect to the frame. Front and rear fender assemblies can be attached to the frame by a midpoint fastener passing through respective apertures in each of the front and rear fender assemblies, through a grommet, and into the frame. A stay assembly attaches a mudguard to the fender assembly, and can involve a swivel clip. Methods are also provided.
