Abstract: A drain trough for recreational vehicles includes a base with two side walls upwardly extending therefrom to define a drain channel for receiving rain water and solid debris. The drain trough is slidably engageable with an existing awning track protruding from a wall of a recreational vehicle via a suspension rod. The suspension rod laterally extends from a top of one of the side walls of the drain trough. This same side wall has a support foot laterally extending proximate the base. The combination of the suspension rod and support foot dispose the drain trough in an upright, functional attitude in order to prevent damage to the vehicle by dripping and accumulating rainwater and debris. The drain trough optionally includes a splice for interconnecting two drain trough sections together, as well as an end cap for preventing rain and debris from exiting one end of the drain trough.
