Hello Chuck,
I wish I had a list of what was installed on each camper, but unfortunately such a list doesn’t exist.
There are two things you’ll want to check to make sure that the B&B RV Fresh Water Gravity Fill Inlet - Recessed Dish Mount - Black # BM78RR will be the easiest swap for you.
First, confirm that your cutout is 3-1/2". Second, check that the screws are 3-1/2" from center to center. The screws sit just outside the cutout, it sounds a little odd, but it works. I went out to the warehouse and double-checked this myself, and I’ve attached an image for reference.
If your measurements don’t line up, no problem. Please feel free to reply with your cutout and hole spacing, and I’ll be happy to find the option that best matches your setup.
Have you been on any big adventures this year? Where did you go, what did you see? Or better yet, what has been your greatest trip to date?
