No personal experience with the Patriot, but I have a friend in our RV club that does and he swears by it.
As far as having a supplemental brake system, remember that many states have either a weight limit (for the toad/trailer) or a stopping distance requirement. And, it only sounds logical to say that a supplemental brake system on a mh/toad combination will stop quicker and in a shorter distance than same combination without a supplemental brake system.
Be safe and remember that it's not only your safety you are protecting but those of us that you might have an encounter with.
