How to Install a Fifth Wheel on a 2013 Chevrolet Silverado


Today on our 2013 Chevy Silverado, we'll be installing the Reese quick-install custom base rails with install kit, part number RP50066-58. Note: We've already gone ahead and lowered or removed the spare tire and both rear wheels for easier access and installation. We'll go ahead and move to the bed with one of the base rails. Using our tape measure, and measuring from the end of bed and not the tailgate, we'll set our base rail into position. Then we'll check it from side to side to make sure we're even from side to side in the bed. Once we have it measured out as per the instructions, using a paint stick, we'll go ahead and mark the attachment holes.

Theyll be the second hole from the outside edge on all four corners. Now with it marked, I'm going to go ahead and use a half-inch drill bit to find the center of the hole. Once we find the center of the hole and go through the spray and bed liner in this application, and down to the metal, we can then take our 1/8-inch pilot bit and drill all the way through. Next I'm going to remove the spare tire rock guard. This will help us to gain easier access underneath.

There are two fasteners that secure it. We'll go ahead and remove those fasteners, and then drop the rock guard down and out of the way. Now, to gain easier access to the hardware here on the passenger's side for the rear base rail, using a cutoff tool, we're going to go ahead and cut out a portion of the heat shield. We'll simply trace out a section and then cut it out. To be on the safe side, I recommend to relocate the wiring here on the inside of the frame rail.

We'll simply unlock the red locking tab, then press on the connector lock, removing it and rerouting it for the time being. We're going to go ahead and cut out a portion of the heat shield. We'll move outside the vehicle and use the custom side bracket, and put it into place on both the driver and passenger's side. As we hold them in place, we'll look up through our predrilled holes to make sure they're centered on the attachment point of our custom side brackets. Now that we're confident that our hole's in the correct position, we'll go ahead and move the base rail out of the way and enlarge it as per the instructions.

We'll be using a step-bit process, enlarging in bit size until we get to our final size of 9/16. Now with all our holes drilled out, we'll go ahead and put the base rail back into place. Now, to put our side bracket in place we'll be using a new 5/8 carriage bolt, 5/8 spacer block, 5/8 conical-tooth washer and nut. We'll use the 5/8 pull wires provided with our install kit to help get our hardware into the frame and into position. First we'll take the pull wire and feed it through the attachment point at the frame that lines up with our side bracket. Then we'll go inside the frame and out the access hole on the inside of the frame. There we can slide on our block and thread on the carriage bolt. We'll feed the block and bolt into the frame and then pull them into position, leaving the pull wire in place at this time. Now go ahead and repeat the same process for our second attachment point. Now with both carriage bolts in place, we can go ahead and side the side bracket on by feeding the pull wires through the attachment points and bringing the side bracket up against the frame. We'll them remove the pull wire, install the conical-tooth washer, teeth of the washer facing the side bracket, and secure it with the nut. We'll do this for both attachment points. Now with both attachment points secured, we'll go ahead and repeat the same process on the other side. Next we'll go ahead and install the hardware for the rear base rail to secure it to the side bracket. We'll go ahead and drop the 2-inch carriage bolts down through the attachment point and through the holes drilled in the bed. Note for this application: we'll need to install the u-shaped spacer blocks between the side bracket and the underbody of the bed. This will ensure that we dont smash the bed corrugation. To secure it we'll be using the conical-tooth washer, teeth of the washer facing the bottom of the bed, then a split-lock washer and a 1/2-inch nut. Now with all our fasteners secured finger tight, we're ready to begin installing the front base rail. Using our fifth-wheel assembly as a template, we'll go ahead and put it into position on the rear base rail and then side the front base rail into place underneath the fifth-wheel assembly. Now that it's in place, we'll go ahead and mark out our attachments points for the front base rail. Using our paint stick again, we'll be using the outside attachment points for this base rail. Once again I'll use my 1/2-inch bit to mark each attachment point's center point of the hole. Then will go ahead and drill them out. For this application, because our attachment point is in the valley of the bed corrugation, we'll need to set the U-shaped space blocker in position so that we dont crush the bed corrugation when we tighten it down. Then repeating the same process, we'll drop our carriage bolts into place and secure it with the hardware again, the conical-tooth washer, split-lock washer and nut. Next we'll begin tightening down our hardware. We'll start by tightening down the base rail hardware first, and then the side bracket hardware. Once we have everything tightened down, we can then torque to specifications as indicated in the instructions. Now with our hitch secured and torqued to specifications, we can go ahead and draw two more attachment points for the base rails. These will be the very center attachment points on the front edge for each base rail. Using our 1/2-inch bit, we'll go straight down through the attachment point and through the bed. Then we'll install an additional 1/2-inch carriage bolt, conical-tooth washer, split-lock washer and nut to secure them directly to the bed. With all of our hardware in place, we can how go ahead and tighten and torque to specifications as indicated in the instructions. Now with all our hardware secured and torqued to specifications, we can go ahead and reinstall the wiring that we disconnected on the passenger's side frame rail, our rock guard. Now with everything reinstalled, we'll go ahead and show you how the new fifth-wheel assembly interacts with the Reese quick-install custom base rails and install kit. We'll put the fifth-wheel assembly into position on the base rails. We'll slide our pins into position and then clip them down. Now, because this application is a sliding fifth-wheel assembly, we'll go ahead and unlock it and slide it out of the way to install our second set of pins. Now with all four pins and clips in position, securing the fifth-wheel to the base rails, we'll go ahead and show you how this head assembly works. We'll use the handle and the dial indicator to mark whether the slide assembly is in the maneuvered and trailered position. Starting in the trailered position, we'll go ahead and unlock the slider assembly, slide it backwards, and then relock the handle into the maneuvering position. Then, once we want to go back to the tow position, we'll simply unlock the handle and slide it back towards the cab, and relock the handle into the towed position. To lock and unlock the head assembly, simply pull out on the handle and slide slightly towards the cab to lock it in the open position. Once your fifth-wheel is in place, to relock the jaw, we'll simply slide the handle forward and help it spring back into place, and then install the padlock supplied with the install kit. Now with our fifth-wheel locked down, we're ready to hit the road, and that does it for the install of our Reese quick-install custom base rails, part number RP50066-58 on our 2013 Chevy Silverado. .
