Safe-T-Plus has some good videos on the installation on Youtube. The installation is basicly the same as for the Roadmaster I installed. If you have a way to get easy access to the underside of your vehicle it really can be less than an hour to install.
In my case the overhead clearance I worked with was the greatest obstacle. If I were going to approach the job again I would find enough blocking to make it a little roomier. I didn't feel that any adjustment was required after the first test drive. Evidently, this is not the norm.
