Depending on your truss configuration, you might want to figure out how to secure the arrangement. The foot print of these base units is not much bigger than the truss itself, so if you do a one-sided arrangement, it will wobble, and you would be advised to weigh it down to hold it in place. I did an L-shaped configuration, so this is less of an issue, though it does wobble if I am pushing or pulling on it. Look good, and the small foot print is useful in my configuration, but I went into this knowing that an L-shaped arrangement was going to be a lot more stable than a single-sided arrangement.
