Equal-i-zer Hitches

Thanks so much for all the info, my buddy uses one (an EQUAL-I-ZER) and said it made a lot of difference in his towing. I just bought a Keystone Outback, towing with a Tundra, the last time I towed in 2007 it was with a F250-- 7.3 and I towed a fifth wheel, I never towed a TT and was just trying to make sure the dealer sold the right hitch...

THANKS AGAIN!
