      Bed Mat, Bed Liner, Bed Coating | Which One is Better for My Pickup Bed?
      If you carry heavy objects, sharp-edged debris, branches, lumber, rubble, and equipment in your pickup truck regularly, you know it doesn't take much for this kind of cargo to leave scratches and gouges on the painted metal surface of your bed floor and walls. Odds are you've experienced this. No matter how gingerly you place items in your bed and tie them down, the unexpected panic stop that always comes up sooner or later still manages to create chaos as things shift around. Maybe you've even felt and heard a dreaded thump behind your seat after heavier items broke free and slid forward hard - leaving a noticeable dent in your bed wall. While these are problems inherent with any metal bed floor, there is a better way to carry cargo while keeping your pickup bed looking good.

      How Can I Carry More Stuff in My Pickup Bed?
      Whether you use your pickup for work or for recreation, carrying a lot of equipment, tools, and gear means you're potentially prepared for a range of situations. But if you can't find exactly what you need and extract it from your truck's cargo area in a timely manner, you're really not as prepared as you think. Consider the last time you couldn't find something in your truck. Maybe a search through the entire vehicle was necessary in order to be sure the item wasn't in the truck before beginning a search somewhere else. How much time did that take? And how was your stress level afterward? Or maybe, perish the thought, you had to buy a new tool to replace one you couldn't find but knew wasn't actually lost for good.

      Pickup Truck Cab And Bed Sizes Are Important When Selecting Accessories
      Americans love to have choices. Buying a dress shirt? Decide solid or stripe, short or long sleeve, cotton or poly blend, button or spread collar, regular fit, slim fit, or big & tall. How about a meal at your favorite steak house? Will it be porterhouse, T-bone, or sirloin? Cooked rare, medium-rare, or medium? With baked, mashed, or French fried potatoes? Thirsty for a fancy cup of coffee? Let's not even get started on options that let you end up with a "grande caramel macchiato with 1% low-fat milk, 2 Splendas, and an extra espresso shot".

      5th Wheel Tailgates Give You Clearance And Aerodynamics
      If you own a pickup with a 5th wheel towing hitch installed in the pickup bed, then you know you need to lower your tailgate whenever you are connecting or disconnecting the trailer from the hitch. If you forget to lower the tailgate? You're buying a replacement.

      Types of Truck Bed Tool Boxes
      Pickup trucks are designed to be very practical, but there’s definitely nothing pleasant about the tools rattling in a truck bed while driving. There’s as well nothing good about leaving equipment and other stuff out in the open, making it vulnerable to the extremes of weather and, even worse, theft.

      Truck Bed Rail Styles
      Actually, truck bed rails serve as extremely handy aftermarket add-ons and are designed for unparalleled utility and appearance. These accessories also protect a truck’s surface from dents and scratches that might occur while loading cargo on a vehicle. What’s more, the bed rails provide the ability to tie down bulky or oddly-shaped objects. Depending on the style, the bed rails can dramatically alter the look of any truck while allowing the truck owners to customize their vehicle by adding certain finishes or lights.

      Truck Bed Rack
      Ladder rack, bed rack, pipe rack – no matter how you choose to call it, this accessory is definitely a very useful and valuable aftermarket product one can ever imagine. This is especially true for carpenters, landscapers, plumbers, contractors, and other pros who use racks for whatever reason (e.g., for hauling tools, equipment, and cargo to the job site and from there, etc.) Same as any other piece of the latest job equipment, a bed rack has to perform the required job, and it’s design should keep pace with modern technology; otherwise, it’s off to the scrap heap.
