Review of Demco RV Fifth Wheel Installation Kit DM8551006

Today we're going to take a look at the Underbed Rail and Installation Kit for the Demco Hijacker UMS Fifth Wheel and Gooseneck trailer hitches. This is a custom-fit part that is designed to fit the 2013 and newer Dodge Ram and Ram 3500 Series truck with either the six-foot bed or the eight-foot bed without the factory rail kit. Now on a custom-fit part I always like to recommend to go to our website, use our fit guide. Put in your year and model vehicle and it'll show you if this will work for your application. Now this complete installation kit is designed for use with the Demco Hijacker UMS Fifth Wheel and Gooseneck trailer hitches. These underbed rails right here will allow for complete access to your truck bed when your hitch is removed.

The rails are not exposed. It does have the four mounting holes right here you have that sit flush with your truck bed, and then when you drill the holes in your truck bed to access these. They do have those plastic caps which are included that would screw in to protect those holes, and keep any dirt and grime from dropping into the holes in the rails right here. Now this is a vehicle-specific design. It reduces installation time and requires less drilling than your universal systems. The no-drill brackets right here will bolt on to the outside of your truck's frame rails and the cross members sit across the top of your frame rails beneath the truck bed and attach to these no-drill brackets.

All these parts are sturdy steel construction with a nice black powder coat finish to help resist corrosion. Rails and all the installation hardware in here is all included, and a nice set of detailed instructions that describe how to install it with pictures. These parts are made in the USA, and that should do it for the review on the Underbed Rail and Installation Kit for Demco Hijacker UMS Fifth Wheel and Gooseneck trailer hitches.
