Weight Equalizer Hitch

What you need for your wayward 17 is an anti-sway bar like this: https://www.etrailer.com/Weight-Distribution-Hitch/CURT/17200.html?feed=npn&gad_source=1&gad_campaignid=11229265674&gbraid=0AAAAAD_vMtkfndD2i950l4YLqmz9qzEJq&gclid=Cj0KCQjwh-HPBhCIARIsAC0p3cdc31bSLdjrFwbPalJMHUHoUNOE9eTfq77tb7sCspJNGr6bPXeLwvoaAlPbEALw_wcB. 

Yes, 15 years towing our 2011 177 using a basic Curt friction bar over 53,000+ miles through blizzards, sleet, hail, thunderstorms, and cross winds in excess of 25 mph without incident.  Tow vehicles have included over the years and in order: '94 F-150 5.0L V-8,manual shift, '08 Explorer front wheel drive 4.0L, V-6 '13 Explorer front wheel drive 3.5L V-6, '11 F-150 5.0L V-8, and since 2020 a '17 F-150 3.5 V-6 with ecoboost.  Really enjoyed the Explorers but wanted a bit more storage for when we go on month long trips boondocking for the most part.  The big thing you want to remember is to have at least 10% of the total loaded weight of your 171 on the a-frame (tongue).  Our 177 fully loaded with 36 gallons of water and prepped for a 30 day excursion weighs in at 2940 lbs.  The minimum tongue weight (10% would be 294 lbs. on the tongue.  I carry a Sherline tongue weight scale (current cost around $165 for a 0-1000# scale) and it reads 340# so I am at 11.6%, well over the minimum 10%, hence, no problems with sway.
