im guessing that was the #9300 Super Farm Class. only thing stock on them is the paint
we have an indoor arena around here too. monster nationals kinda suck... but i think it was 2 years ago now the guy that started it got ran over by a monster truck here!They are a ton better watching outdoors for sure. We have a small arena here too, makes watching motocross, monster trucks, and tractor pulls very boring. I no longer waste my money going to them unless they have one outside or in a bigger arena within a reasonable driving distance.
