You did not buy that deluxe RV trailer to sit on cinder blocks by the garage all year. You bought it to hitch up to your pickup truck and tour the country, experiencing the beautiful landscape one mile after another. Put your mind at ease with every mile of your journey by installing your 5th wheel hitch the right way with CURT 5th wheel brackets. CURT semi-custom 5th wheel brackets are designed to work with CURT universal base rails when installing a 5th wheel trailer hitch. The semi-custom brackets fit on certain trucks that are unable to use parts from the universal installation kit due to limiting obstructions on the underbody. Together with the universal rails, the semi-custom brackets create a solid attachment point for your 5th wheel hitch.
