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.
A typical half ton truck (chevy 1500, ford f-150, etc) weighs anywhere from 2.25 tons to 2.75 tons (4500-5500#). Of course extended cab, regular cab, and crew cabs â¦account for this varying weight. Next you have 3/4 ton trucks (C20, 2500, f-250, etc). Again, they can be long bed, short bed, extended cab, crew cab, etc.
