Perhaps I sounded too much like an alarmist. Your trailer will be fine. I never had even a hint of sway with my 21RB but the tongue weight has always been less than the 10% of trailer weight that seems to be the target ratio. I'm sure others more experienced than me will chime in and explain the causes of sway but one goal is to have a well balanced trailer. I never heard of too much tongue weight causing sway. I don't think the tow vehicle has anything to do with affecting trailer sway but it has a lot to do with how it reacts to it. Obviously the "tail wagging the dog" is much less affected by a large dog. But I think it's possible to have trailer sway regardless of the tow vehicle size. Again, I think others are better suited to explain more about trailer sway.
Don't take this as a recommendation but what I did to ease my concerns about trailer balance is weigh the tongue with the fresh water tank full/empty. I also factored in the weight of propane
as if the tanks were empty and full. All of the weighing
was done with the trailer outfitted as if it was actually being used for a trip.
