Welcome to this forum and your 24/7 owners manual.  Good to hear you had a great experience with your 196 and Ridgeline combination.  Tongue weight will take a lot of guess work out of having a good towing experience.  Our 177 fully loaded for a one month trip and 36 gallons of water (tank behind axle) weighs in at 2940 lbs.  To eliminate/reduce sway you need 11% or more of the loaded r-pod weight on the tongue, so take 2940 x .11 = 323 lbs.  We carry a pair of 12v batteries and also a pair of 20# propane tanks on the tongue.  Using a Shurline tongue weight scale the tongue weighs in at 340 lbs.  For 12+ years we have only utilized a $40 Curt friction bar, tow vehicles include 2wd Ford Explorers and a couple different F-150's, the one used now is a '17 F-150.  Weather conditions encountered so far have been snow (including blizzard conditions), sleet, hail, heavy rain, even creeping on back roads at 1-3 mph when roads had water 10" deep (glad we installed the riser kit!), and cross-winds in excess of 20 mph.  No issues or problems have been encountered thus far, we are very satisfied with the simple friction bar set-up.

Hope you have many more memories to be made with your set-up and can get out some more this fall; enjoy those fantastic autumn colors!
