I would prefer it over their previous TrailAir TriGlide. Had one and hated the roll and clunk on take off. Was noisy while traveling too. Still ugly as sin though so I went with a 5th Airborne this time around. Fits under my factory fiberglass pinbox cover and disappears. Functions nicely too.
Here was my TrailAir which looks similar to the FlexAir.
Here is my 5th Airborne.
