-Also leave a bit extra hose length at the top, so that you can "curl" the tops of the hoses back down. This will prevent the ingress of water through the hoses in case when power washing the vehicle. It isn't a bad idea to stuff some very thin (breathable) cloth (like a band aid material) in the tops of the hoses, to prevent ingress of dirt and insects inside.
