Step 01: Truck Preparation

Wash and dry your truck’s bed and tailgate areas thoroughly. Clean bed and tail glued with adhesive tape holds tightly the rug. Get a place where you can work for hours without any disturbance. Buy all the things you will need for this project. Purchase a good brand of truck cap. While purchasing keep three things in mind. The first one is the storage or the toolbox for storage. Second side access doors, as this features, is more convenient as it opens up for air ventilation and for view. The third feature should be aluminum framing, it may be a little high in price, but spending once and take the great advantage of it for the long run.

Step 02: Weatherproofing truck cap

Before Camping, make sure to weatherproof your truck. Weathering and securing the cap of the truck came first in the list of DIY. Campers need a place to sleep peacefully, without any hassle. Rains bugs and insects are the major problems while camping anywhere. To protect yourself from them and to protect your truck bed weatherproofing is a must to do. When we purchase the truck cap, we didn’t provide by all the materials to secure it to our truck’s bed. Mainly what is done is the utility cap is placed over the truck bed, and with two clamps from the passenger side is secure and screwed in a bolt on the driver side. But this is not it. Converting a truck into a living space needs some extra effort.

For weathering you will need, washers for bolts, camper mounting tape, 0.3’’ threading with 1.5’’ bolts, locking nuts, hammer drill with socket, wrench, and your safety measures aids. Start this by applying adhesive tape to your truck cap. Lay the truck cap in a clean surface upside down to apply adhesive truck bed insulation tape. Start applying the around the entire bottom of the truck cap, except the rear end. Because if you cover the rear area then you won’t be able to open and close your tailgate. And add some layers of tape to the bulkhead to ensure nothing gets in or out.

Fix with bolts:

After that mount truck cap on the truck bed. You may need a helping hand here, ask for help to someone while doing this. Flip the truck cap with the right side up and place it onto the pickup truck bed carefully. Fit the truck cap evenly on both sides of the truck bed, and secure truck cap with bolts. For this, you will need two aluminum hardware clamps. Climb up into the back of the truck and apply the clamps between the truck bed cap and rail. If you have a toolbox on the driver side then you could only clamp the passenger side down.

Now drill to fix it:

If your truck bed length is 6.5’’ than You need to drill three holes and if bigger than that then four holes. Drill on both sides of the truck cap. Maintaining the distance of 25’’ to 30” apart. Some pickup trucks have default holes. If your truck doesn’t then don’t fear to get the new holes. Place the bolts with washers in the holes. Once all bolts are in place, screw all of them to secure the truck cap in its place. In the tail part near the rear light find the hole to the assembly for the wiring of the truck cap tail light. If there is no hole then drill a small hole for further use. As you read on this blog you will get to know many things, here the hole, basically, it is for brake lighting.

Lastly, remove the tailgate assembly from the truck cap to locate the wiring. Take the wire and make a cut. And mount the brake light. The wiring may cause a little puzzle for the new users. Now connect the high mount stop light wire with the truck’s brake wire. After wiring is done correctly, your process of weathering is complete. And the truck is weatherproofed.

Step 03: Installation of Bedrug LIner

While choosing the liner, go for bedrug liner. For truck bed campers Bedrug liners are easily available in online stores with accurate measurements. Bedrug liners are comfortable in comparison with any other liner. It comes with three to four inch cushioning.  These are the best comfortable truck bed floors.

There are two main parts (side wall and bed) of the bedrug liner. Align the sides of the bedrug. To fix the two main parts manufacturers provide zip lock, once properly aligned, zip sides into place.

Note here:

Do not place velcro down until you’re sure the Bedrug is in the correct place. After assembling, take the bedrug liner and place it on your truck bed facing upward. Bedrug position front to rear and left to right by aligning all edges and tucking corners into place. Take rubbing alcohol and clean attachment areas thoroughly and allow them to dry.

Leaving 1″ of 2″ wide Hook Fastener exposed for future attachment to front edges of side panels.

Middle 1’’ * 2’’ row of hook fastener is not applicable on some models. Attach Hook Fasteners to BedTred Sidewall Panels. Find the 3, 10″ long Hook Fasteners and apply above wheel well and upper tier loading areas. Do Not Locate in wheel well itself.  At 45° angles apply 6 pieces outside of each end of the wheel well. After that apply 2″ pieces on top and rear edges as needed.

You will get extra adhesive strips in the kit for future use or if the installer deems more fasteners are necessary for better fit/appearance.

Step 05: Bedrug floor and Bulkhead Installation

First roll the bed rug floor towards you, exposing the 1’’* 36’’ fastener located on the Bedrug bottom. Remove the film of the velcro fastener and roll the bedrug floor and sidewalls back in place. Now firmly press the bedrug top surface for 10 seconds to ensure velcro adhesive attachment. Repeat the same way on the other side. To determine the best location, fit the top Erde of bedrug bulkhead to the top edge of the body panel.

While attaching clean attachments areas thoroughly with rubbing alcohol and allow to dry. Now remove the film working from bottom to top and center of part outboard. and roll the top edge back in place. Press firmly the bed rug top surface for 10 seconds to ensure adhesive attachment.

Other optional features for beds with tie-down hooks:

Some beds are equipped with load extenders, some hooks may found and other functional equipment anywhere located on the floor. So for these, the installer is a little different. Create a cut mark or cut a small slit in the appropriate area allowing the equipment to pass through the surface of the bedrug. And do not through any seams or sewn lines.

Remove the equipment before the bedrug installation, and then reinstall the equipment on top of the bedrug after once the installation of the bedrug is complete. Too easily locate fastener holes use an awl after bedrug is positioned for best fit, and make sure to re-torque tie down fasteners to the OEM  specifications.

Step 06: Installing BedRug sidewalls and Tailgate:

The rear vertical corner of the bedrug should be positioned to match the pillar surface. Start from the front and working reward begin removing the film from fasteners bottom to top and from back to front. As told beforehand press the bedrug side walls for 10seconds to ensure adhesive attachment. And repeat the same to the other side. Note here if you are using the bedrug in conjunction with a bed extender, cut the slits of the D pillar area to allow access to attachment holes. Now come to tailgate, rotate the bedrug up to access tailgate fasteners. Take rubbing alcohol and clean attachment areas thoroughly and allow them to dry. Use adhesive promoter to plastic cap if applicable. For truck bed camper bedrug is the best liner.

Remove film and align the edge of the bedrug tailgate section to the top edge of the tailgate. If you get a 4298 adhesion promoter pack in the hardware kit then do not adhere the hook fasteners to the factory plastic tailgate cap. Note here most models are designed to adhere to sheet metal just below plastic tailgate cap. Place the bedrug tailgate. Press the bedrug tailgate for 10 seconds to ensure adhesive attachment.
