1. You can order whenever you want and just specify that you want 2016 model year.
2. We won't change any colors until the mid model year refresh in September.
3. Chassis will not affect any changes to our portion.
4. No major changes expected form Ford or Chevy (that I know of).
5. No Major changes expected on our end either, however I am always tweaking little things (adding LED lights to the sewer area, changing trim or components). If I can make the product more durable or useful I don't ever wait for model change.
