The main reason I went with a larger trailer was to accommodate 2 dual sports in the future. I also have to move small amounts of furniture on occasion and the trailer doubles as a cargo unit. Here's my set-up.
In freight trim the Condor chock folds flat and can be stored against the front wall. It attaches to a steel bracket bolted through the floor to a reinforcing steel plate. The bracket only sticks up about 3/4" and is about 2"x4" in size.
The beauty of the chock is that you can ride the bike into the trailer, and then dismount and set your tie downs. It's a single person job.
The tipover wings provide a perfect tie down point. The floor cleats are positioned to provide a forward pull.. The front wheel is held securely by the chock and a light cam lock strap is run rearward from the grab handles on each side to stabilize the rear. On a long trip I'd probably double up on the tipover wing straps just for piece of mind.
Here's the ST ready for transport. This is much more elaborate than most riders would need but I'm looking at hauling the bike south for a few months during the winter in a year or two. I wanted the room the work on the bike if needed.
New, a trailer with the heavy ramp door and the reinforcement for the floor cleats and wheel chock, is pricey to say the least. I was lucky and was able to find a used one. It's a 6'x12' with a 6' height, single axle. One thing I recommend are the rear corner jacks. These allow loading and unloading when the trailer is not hooked up to a tow vehicle. HTH
