Heavy-Duty Bed Reinforcement System for the Ultimate 5th Wheel Connection

The Ultimate 5th Wheel Connection Full Bed Support System is designed to reinforce your truck bed when towing with a gooseneck-mounted Andersen Ultimate 5th Wheel Connection. This heavy-duty support system distributes hitch load more evenly across the truck bed floor, helping reduce flex and maintain structural integrity under heavy towing conditions.

Engineered specifically for compatible Ultimate gooseneck mount configurations, the Full Bed Support System enhances stability, improves load distribution, and provides added confidence when towing larger 5th wheel trailers.

Why Choose the Full Bed Support System?

  • Distributes hitch load across a wider surface area of the truck bed
  • Reduces bed flex under heavy 5th wheel towing loads
  • Improves structural stability and long-term bed protection
  • Designed for gooseneck-mounted Ultimate 5th Wheel Connection systems

How the Full Bed Support System Works

Andersen Hitches gm truck support bracket separate components 2048x

When towing with a gooseneck-mounted 5th wheel hitch, vertical load is concentrated at the mounting point in the truck bed. Over time, this focused pressure can contribute to bed flex, especially under heavier trailer weights.

The Full Bed Support System installs beneath the Ultimate 5th Wheel Connection base and works to spread the load more evenly across the truck bed structure. By increasing surface support and reinforcing the contact area, it helps maintain proper hitch alignment and reduces localized stress on the bed floor.

This added reinforcement is especially beneficial for drivers towing heavier 5th wheel trailers or those looking to maximize long-term truck bed durability.
