After almost 15 months of extensively towing my 2020 16ft
Caravel with a 2017 Tacoma, 4X4, extended cab TRD with tow package, my sway control & weight distribution equipment still sit in my garage. It was used extensively with my previous 17 ft trailer which was a foot longer, but lighter, 10" narrower, but had sway issues. I currently travel with full water, but otherwise after years of towing a trailer, pack pretty much as a minimalist would, tailoring to each trip. Gen, etc. How can anyone be a minimalist pulling a loaded AS with solar, lol. I travel over the passes of Colorado, the 50 mph winds of W, Texas, NM., several times thru downtown Houston, Austin, & Dallas via interstate. Best of all I've survived the crazy Texas big rig drivers. I drive at 65-70 mph when possible. Tires 75PSI.
Maybe chalk it up to Airstreams engineering, don't know.
Keep in mind that its tons safer towing a 16 ft trailer vs a 25-30 ft trailer if your towing with a more than adequate truck. Every foot of length when it comes to wind & weight distribution add to the degree of difficult. My fresh water tank sits in the front of the trailer, still being close to the axle. The combo tank is just behind the axle, with rear storage also very close to the axle.
One important thing I do to keep myself & others safe is closely monitor my tires at every stop & then replace with a quality tires every 3-4 years.
Since you have past towing experience, I'm sure you'll figure it out. As you know different tow vehicles, cargo weight, number of passengers, pets, toys, etc. can make a huge difference when towing.
If you were new to towing I would say go with sway, weight distribution hitch every time.
