so your telling me if i go to the pro series there gonna run unlimited and production monster truck together? I think not. What your thinking of is lack of people at a local track. The only reason they combine them is so we can race, if they didnt combine the 2 then nobody gets to race. At the pro series they seperate the 2 classes because theres always plently of people to do that. And this will become a rule for next year for fuel tanks. I sure hope they ban those trinity tanks. Make um 125cc or smaller. Even if they do allow them you still have to add fuel into the tank for your maditory pit so theres really no point in running a bigger tank then. Kinda defeats the purpose if your adding fuel when you dont need it. Besides my truck will be slightly lighter and A WHOLE LOT FASTER
