New to TT (long time pop-upper) WD hitch probs

I saw a response here that indicated the friction sway component was at the L brackets. That is not the case. It's at the head.

As long as my tow vehicle and trailer were on similarly level ground, it hasn't mattered how well (parallel) they were for hitching/unhitching. Mine has been at nearly right angles before. Also as previously noted, you can leave the bars off the trailer until you maneuver it into a more amenable position.
