Only 90?

I wonder how that would have turned out for anyone else in the vicinity, if the test revealed a problem?

Your just jealous. Jesting aside, there was no one around and my tires are rated for 100. You can have something go wrong at 55 to.

Rated for 100.....kind of made me think of all the times as a dumb teenager, that I had my car over 100. No idea if the tires were speed rated back then. Kind of doubt it but there wasn't any sway as I was hauling something other than a TT .

I've done something of the kind, too. Not 90 mph, but 75 mph, and my tires were only rated to 65 mph. It was just a test for a brief time, and the tires were in good condition and pressure recently checked. The rating relates to the tire's ability to withstand the heat build-up that occurs during sustained driving at speed.

I gradually accelerated from 55 mph in 5 mph increments. At each increment I generated a little tail wag to see how the trailer would respond. There were no other cars nearby, and my hand was near the brake controller if there was any tendency toward undamped sway. There was none; the Scamp came right back in line.

I stopped at 75 because (1) it was the speed limit, and (2) it is well above my maximum normal towing speed. I was something I did to evaluate whether I wanted to continue to carry two bicycles on the back of my Scamp, having read the many warnings on this great forum. Having satisfied myself that my set-up was stable up to 75 mph, I returned to my usual 62-65 mph.

Three main equipment-related factors affect stability: loading, attitude, and vehicle geometry. Beyond equipment, stability is also affected by speed and environmental conditions.

For loading you want weight low and near the axle, with enough forward bias to achieve a tongue weight of 10-15% of the total trailer weight. Weight on the back of a trailer, even if balanced by weight forward, is not ideal, which is why I wanted to make my test. With the Lil Snoozy, the main storage compartment is forward under the main bed, which is good for stability. The water tank is also just forward of the axle, also good.

Attitude should be level or slightly tongue down for a single axle trailer (level or slightly tongue up for a twin axle). That's easy to correct with the right ball mount. The Lil Snoozy's shape likely makes it less sensitive to small changes in attitude.

Vehicle geometry is more complex. On the trailer side, a longer ball-to-axle length improves stability. On the tow vehicle side a shorter ball-to-rear-axle distance and a longer wheelbase are good for stability. Every time you make a steering correction, the ball moves slightly in the opposite direction. A long rear overhang on a vehicle combined with a short wheelbase magnifies the effect. Most people tow their Lil Snoozy with a pick-up or larger SUV, which generally makes for a very stable combination from a geometry perspective.

I have not read a single report of unusual sway involving a Lil Snoozy.

Our tow vehicle is a Ford Expedition, regular length. It makes for a very stable combination. Last year going through Montana, SD, and Nebraska we ran at 75 all day with no problems. I pulled the Snoozy the first year with my Ranger. It was also very stable.

Thanks everyone for the replies. We hopefully will put our deposit on a snoozy this summer.
