My previous package (years ago) was a 1990 Ford Aerostar V6. I towed a 1973, 2700lb Glenelle. While the van was a light weight, the trailer was a Sherman tank. I also had a class 2 weight distribution system on it. It towed beautifully and never one concern.
Now I tow with a Ford Explorer V8 4x4/ AWD. I tow my T1350 that weighs 1750 lbs dry weight. I searched online and contacted many, many RV shops plus one very reputable hitch installation place that has been in business for decades. All together they said I do not need a weight distribution system.
Mines tows as though there's nothing behind me. I have encountered some windy situations but not any real heavy windy situations.
I think what I would do if the wind ever got to the point of being scary I would hook my Explorer to the trailer as an added anchor while in the campsite.
