No I haven't.. There is a limit on width in the stock class. The limit is 80". So I am waiting to here on this since I am around 84"... If I have to run the Pro Mod class, I may not go and just go to Summit Truckfest and run the rocks there.
Pro Mod class can run up to 40's. I have a friend with 38.5" boggers that said I can run them if I want, but I dont know....
