I have a 2000 dakota 4x4 that I tow way too much with, it has a hollow front bar, I have a 3 parts durangos, 2 have the same size bars but solid and the 01 R/T has an even bigger bar that is solid. I was wondering if I should install the same size diameter solid bar or should I just put in the R/T bars?

I have taken off the bars temporarily for hunting season for when I am out in the woods so just trying to decide witch one to put back on in 2 weeks. Dakota is a V6 5 speed all the Durangos are V8s.
