Troubleshooting Trailer Bounce With A 2022 Winnebago 2108FBS Micro Minnie Travel Trailer

Question:

I am towing a 2022 Winnebago 2108FBS Micro Mini with a 2021 F-150 Sport with a tow package and Husky Centerline WDH. I experience a shuttering bounce at 65 when traveling over concrete due to the expansion joints. My wife has motion sickness, and it was way too much bounce for her. It was only tolerable if I slowed down to 55. What can be done to smooth out the ride so it is tolerable at 65 mph? I don’t know if a RAS 3611-Y kit will help, or a Sum Spring helper on my trailer.

With your trailer being so new it sounds to me like the real issue is with your weight distribution hitch. Your Husky Centerline is most likely rated too high for the tongue weight of your trailer and is giving you this rough bouncy ride. The GVWR of a 2022 Winnebago 210FBS Micro Minnie is showing up as 5,500lbs so you would want your WDH to be rated in the 400-600lb tongue weight capacity range.

I recommend the Fastway e2 Weight Distribution w/ 2-Point Sway Control # FA92-00-0600. This hitch utilizes two points of steel-on-steel friction to prevent and correct trailer sway, while sway control brackets help to ensure that your trailer stays in line with your tow vehicle. It's perfect for smaller trailers with 250lbs - 600lbs in tongue weight. An adjustable shank is included as well to help keep your hitch level. It does not come with a hitch ball but will fit hitch balls with a 1-1/4" diameter shank, so you might be able to reuse your current hitch ball. If not, then you can use # A-90 for a 2" ball or # EQ91-00-6100 for a 2-5/16" ball.

The correct rated WDH should solve your bouncy issue but you can still beef up the suspensions of the trailer with one of the following options:

For each axle you can use the SumoSprings Trailer Helper Springs # TSS-106-40 if your leaf springs are underslung or the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-107-40 if your leaf springs are overslung.

If you have a tandem axle then I recommend installing a shock system like the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 3,500-lb Axle # RM-2450. This system is designed to fit 2-3/8" diameter axles and will greatly reduce the trailer bounce, chucking, and porpoising that you have been experiencing.
