Covercraft – Cab Forward Truck Cover (Part No.C15857D6)

Cab Forward Truck Cover

from

$838.99
Cab Forward Truck Covers are designed as a quick and easy cover solution to protect your truck’s cab and hood. Sunbrella provides protection and years of service in intense sun climates like Arizona and other areas of the Sunbelt, where UV rays can rapidly degrade the paint and interior. Because of the use of acrylic fibers, which are naturally UV resistant, Sunbrella has long been the recognized leader in longwearing marine fabrics for bimini tops, sail covers and deck enclosures. Besides marine uses, Sunbrella is also used for commercial awnings due to its ability to provide UV blockage, along with a rich, woven finish. The acrylic fibers are solution dyed, before the fabric is woven, to assure the color goes all the way through the fabric. Using a special finish process, the material is then softened for use as a truck cab cover fabric. The fabric is exceptionally strong and, coupled with its UV resistance, it also makes an excellent cover for RV’s and trailers that spend extended time stored outside.

Product Features:
  • Custom Protection for Front Half of Pickup
  • Great for Use with a Camper
  • Protects Interior From UV & Reduces Heat Build-up
  • Easy to Use
  • Cab Forward Covers Available in Multiple Fabrics

$117.99
CURT 5th wheel base rails are industry-standard, meaning they can be used with any 5th wheel trailer hitch with industry-standard anchoring points. They are compatible with virtually all CURT 5th wheel trailer hitches and many competitors. Installation of CURT universal 5th wheel base rails is quick and simple. They mount with high-strength hardware, providing a solid mounting place for a new 5th wheel hitch. 5th wheel base rail bolts and other hardware can also be purchased separately to aid in reinstalling used rails. To protect our 5th wheel base rails from corrosion, scratches and UV damage, we coat each one in a co-cured finish of A-coat and powder coat. This gives them the tough skin they need for hauling that RV trailer, flatbed or other heavy-duty trailer and gives you the confidence to tow wherever the horizon leads. This set of 5th wheel rails is rated for 25,000 pound gross trailer weight and has a carbide black finish. Knowing that your 5th wheel trailer hitch is properly mounted in your truck bed is vitally important to the success of your towing. Without a firm attachment point, a 5th wheel hitch is rendered useless to your tow vehicle. When you choose a 5th wheel hitch for your pickup, install it with confidence with a CURT 5th wheel bracket kit and a set of CURT 5th wheel base rails.

Product Features:
