2006 GMC Sierra 2500HD
The highest fifth-wheel-hitch rating for the 2006 GMC Sierra 2500HD is 16,100 lb, the top of 40 rows transcribed from General Motors’ 2006 GM Light Duty Special Applications - Trailering Information. That row is printed for the 8.1L V8, Regular Cab, 2WD, 4.10 axle, GM model code C25903, Automatic or manual transmission. Most configurations are rated lower: 39 of the 40 transcribed fifth-wheel-hitch chart rows for 2006 are below 16,100 lb. The other cited maximum for the 2006 GMC Sierra 2500HD is 12,000 lb on a conventional hitch. Across 80 manufacturer chart rows for 2006, ratings run conventional 9,700 lb to 12,000 lb; fifth-wheel 9,700 lb to 16,100 lb; the engine, cab, axle ratio and package on your truck decide its number.

Bed, tongue weight, and wheelbase
The trailer rating is one limit. The bed has to fit the load, the tongue or pin has to fit in payload, and the wheelbase is the column the chart uses.
- An illustrative 10 percent of the 12,000 lb conventional maximum is 1,200 lb of tongue weight. This is not a measured load or recommended percentage; actual load may be higher.
- An illustrative 15 percent of the 16,100 lb fifth-wheel maximum is 2,415 lb of pin weight. This is not a measured load or recommended percentage; actual load may be higher.
