We also love our Sabre, I'm sure you will like yours, too.
The best recommendation I could make about your PDI is take notes & pictures during the walk around. There is soooo much information presented, taking notes will help.
Also, have you checked with Sabre about installing a Sidewinder? Some manufactuers do not recommend it as it can cause excessive stress on the frame.
