This is mainly for those of you who drive strait axle swapped trucks. How much do you tow and how does it handle. I'm getting tired of this IFS{starting to make noises} but I regularly tow 25k-30K LBS. I will be buying a dually in the future if all goes as planned but for now this has to work and work good.
I was also wondering how your milege is affected? I'll be running the least ammount of lift and 35"s or 37"s
