People support what works for them, naturally. When I first got my AS it came with an inexpensive Curt hitch. Sure I got a greasy at every interaction but it worked. I commented a few times on this forum about those who would spend so much on a hitch as those Hensley, 3P 'ers. Then I bought new tires for my tow vehicle, MS/2s and on my next trip my trailer was swaying all over the place. I checked height, etc. and it was ok. I took my father along for a ride and he could not believe, "almost has you in the other lane," the difference. I took people's advice here and bought a used 3P. VERY nice hitch. I will say though that when I got it I immediately found that the original owner had been shipped two different weight bars. Sean from Propride sent me the correct one with exchange. My first run was amazing, the truck and trailer moved as one. When a semi passes, the movement is less BUT what movement there is, is as one. I do not have ANY sway to speak of. If you decide on it, get the largest weight bars, not an option. My AS tongue weight is listed as 860lbs but at the CAT scale it is 990lbs (1000) you need the extra.
I installed my 3P and I am a beginner mechanic IF THAT. It took me two sessions and quite a bit of time working slowly alone. The truck receiver/stinger part is not bad- just figuring out if you turn the L up or down based on truck/trailer height and a couple monster bolts. The second part I ran into an issue with my LP tank tray. I had to buy Nylon spacers to raise it so that I could mount part of the hitch on the tongue. And, yes, like AG & AU said, get something to lift that heavy hitch head in place once you get to that. This may sound dumb but it took me a while to wrap my head around how the pieces worked together, so, in spots the directions sometimes left me pondering (obvious novice, "ok it says to tighten that here but how do you get it on there?) Hey my trailer doesn't go down the road beside the truck so I must have done something right! One perk is that I can also drop my tailgate while hitched unlike before.
