I use to use one of these on my Lazy Daze. (E450) Worked fine. Just be mindful of it blocking air intake to your radiator on a hot day possibly towing on an uphill grade. Keep an eye on your heat gauge. Otherwise should be fine.

I found this, Fia GS902-16 Custom Fit Grille Bug Screen, on Amazon ($36). There were several good reviews & a 2016 Winnie (E 450) owner posting good comments plus pics. I've attached a kink. I also order the screen & will post once I have it installed. Thank you for the support! I do have start up issues with my Onan 4000. I don't have any codes written down, yet. I'm sure there's some good posts about these Onan's. https://www.amazon.com/dp/B001F5FS2Y...roduct_details
Hi MUBULLDOG,
So it looks like the radiator opening on the F-trucks is about the same as for the E-450. Being on the outside will make it easier to install, remove, and clean. I definitely want to see how you customize for the bumper and lower spoiler openings.
Thanks, Eagle5
