The Low-Down on the ThinLine LED Trailer Tail Light Video

The ground wire (neutral) is the white wire of the ThinLine LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 15 Diodes - Clear Lens #STL64RCB. The black wire is the power wire for the taillights and the red wire is the power wire for the…

There are a few different replacement caps for the various Titan actuators. Replacement #T4830601 that you referenced fits model 10 and 20 actuators. Since it doesn't fit you must have one of the others. Cap #T4480701 is for model 60 and Aero…

A leaf spring should be replaced if it is badly rusted, has cracks or breaks in its leaves or if it is sagging. A 14-year-old travel trailer could certainly be in need of new leaf springs. The keys to selecting correct replacement leaf springs are to…
