AI picks by need

A hitch-mounted support that carries long items well past the tailgate.
Not for: Trucks without a receiver hitch, or loads needing more than an end support.
What the AI looks for in Truck Bed Extenders
- Mounting style
- Tailgate-based extenders suit short overhangs. Hitch-mounted ones handle long loads. The overhang length decides which type works.
- Tonneau compatibility
- Check clearance with your cover and bed rails. Many extenders conflict with covers.
- Fitment
- Match the truck model and bed width. An extender that does not fit cannot lock properly.
- Legal flagging
- Follow local rules for marking loads that extend past the vehicle. Overhang laws vary and are enforced.
Brands that matter
- AMP Research: Premium bed extenders and steps.
- Darby: Hitch-mounted load extenders.
- Lund: Truck bed accessories including extenders.
What to avoid
- Extenders that rest only on the tailgate cables
- Exceeding the hitch tongue weight with a hitch extender
