Thank you for your submission!
Sounds like you’re using the application guide like a pro!
However, since your Fleetwood is built on a Workhorse chassis, and not an F-53 chassis, the best way to use the application guide is to start from left to right.
In your case, entering the Coach make is not necessary. The chassis year, make, and model would suffice.
The only thing that I am not confident about, is the model, W16. We list part numbers for the W20, W22, and W24.
Feel free to email me at [email protected], so I could ask you a few more questions, and maybe get together with our engineer, so we can see if we can come up with something for you!
