I also question your cut off point. My F5 is considered a 2 ton in Canada. I don't share much with the F1 and F2 models. 95% of the info I need I get from the big truck guys. And because of my Marmon- Herrington conversion my payload is around 5 tons. You really should base it on tire size. I use the same rubber as the big trucks, why? Because they consider us a big truck. They are set up for light trucks and commercial trucks. And while I'm whining why don't you guys fix your Profile choices to include F4, F5's etc. instead of making us use F450, F550 etc.. That's like a 2 minute fix for the webmaster, because the way it is set up now kinda says "we don't really care what you drive".
