hmmmm.... I don't know who 'told' you that, but my Palazzo 33.3 from later 2014 has never needed anything.
But, what some don't understand about the tires on these diesel pushers is that in order to have the optimal smooth and 'less pulling' ride, you need to weigh your coach, with axle weights separately for both front and rear, and then refer to your tire manufacturer's guidelines for the PSI for the fronts and the rears... you may find that you have your tires way over inflated. Don't go by the 120psi stated on the tires, you'll probably find that 85-95 is a MUCH better ride, and more along the lines of what the weight to PSI ratio is for your axles/tires.
Secondly, if you have an 'pull' to either drive tire, you may actually only need a tire swap, which is what we found early on when ours seemed to 'pull' to the right. Freightliner's Oasis shop, in Gaffney where the chassis are built, simply swapped the two front tires and we had no more issues. But, any truck tire shop can do that for you - easy.
