I used a Weight Distribution hitch with my Dually and my 31 ft TT...no I didn't need it...but the rig rode so much better with it. I absolutely hated that truck, it was so impractical in my day to day life. While excellent for pulling a camper it was terrible as a daily driver into the city. I'm not retired and I don't work in the field. I'm an office jock so for my needs a smaller truck was just more practical.
A Weight Distribution hitch is not a band-Aid...it's another way to do something and it makes it very practical and safe to tow a heavier trailer with a half ton truck or SUV.
I crack up at the bandaids comments, I have seen guys make that comment and in their signature it will say timbrens or airbags.
JMHO only.
Thanks!
