Buyer’s Guide: What to Consider

Choosing the right 5th wheel hitch for your GMC puck system involves key factors. Here are five points to consider before making your purchase.

• Weight Capacity: Match the hitch's gross trailer weight rating to your trailer's weight. Overloading can cause safety issues, so choose a hitch that exceeds your trailer's weight.
• Bed Length Compatibility: Short-bed trucks (under 8 feet) often need a slider hitch to prevent cab contact during turns. Long-bed trucks can use fixed hitches for simpler installation.
• Puck System Fit: Ensure the hitch is designed for your GMC's factory puck system. Some hitches include adapters for broader compatibility across Chevy, Ford, and GMC models.
• Articulation and Pivot: Look for hitches with dual-axis or full articulation to handle uneven terrain. This reduces binding and provides smoother towing on rough roads.
• Ease of Installation: Quarter-turn anchoring systems allow quick install and removal without tools. Consider how often you'll remove the hitch and choose accordingly.
