Driving my transit connect for the first time I quickly realized it needed sound deadening. I pulled every panel and installed 10mm deadening everywhere I could find a metal panel. Then added corrugated plastic to cover where there was none, doors, walls, rear ceiling. I also added a second light in the rear and switched them both to LED bulbs. BIG upgrade. Seeing how I use this van for work, I build shelving for totes. I am loving this thing so far!
