I should have been more clear. Too much catalyst dissipates with an acrid, almost vomit type odor, often accompanied by a pinkish color shift and/or haze. This is a different smell than the normal outgassing of formaldehyde. In my opinion, companies that use a diluted catalyst are just trying to sell more product. A gallon of catalyst at 3% lasts a lot longer than a gallon at 10%. 3% ratios are not difficult to measure with reasonable accuracy.
Crew weight. There is a wide range of crew weights that is competitive in the Viper 640. The average of all crew weights at the 2015 North Americans: 550 lbs. Crew weights ranged from a low of 490 (#10) to a high of 650 lbs.
Curb weight for the Raptor SuperCrew is pegged at 6200 pounds, up about 200 from the Raptor SuperCab. Payload capacity grows 100 pounds to 1030, and the maximum tow rating jumps from 6000 to 8000 pounds. SuperCrew models also receive a 36-gallon fuel tank, versus the 26-gallon unit in two-(full-)door trucks.
