I recall seeing that as well, they were leaving PST with the adjusters cranked down.
With a 16:1 box? Shouldn't be that bad. The steering effort below +5° of caster is significantly better than what it is at +6.5°. But it's all relative, I've heard guys with similar set ups as that complain about the manual steering. Meanwhile compared to my set up that would be a piece of cake.
