Blue Ox Patroit Vs Invisibrake

Somewhat confused. Purchased a 2006 jeep liberty sport to pull behind Class C Jamboree. The Patroit brake unit looks like I need to install every time I move on down the road. The invisibrake unit looks like a one time install and then just go. So, what is the benefit of each as it relatesinstall and to towing. I have an installer who recommends the Patroit. I have to admit the invisisbrake seems to need more removal of jeep interior according to avail video.
Your suggestions etc would be greatly appreciated.
Thanks in advance for all your advise.
