I know where my rooftop A/C is, I know what the two antennas look like, the plumbing vents, and the interior vents, but this sort of long rectangular thing with a metal deflector in front of it makes no sense. I have an AC-powered fridge, no propane on it, this is roughly over the refrigerator. I do have propane heat and propane/electric water heat. 2019 Jayco toy hauler.
On my roof and I have the exact same one, but mine is black, thats the vent for the refrigerator. Is your refridgerator mounted sideways? If you look carefully, it has a aerodynamic slope on one side and thats the side that faces into the wind. Mine is horizontal to the trailer with that part facing into the wind. Remember, if you have a propane fridge, there is a flame behind the fridge and it must be vented. So on the side of the RV will be a hatch to the fridge and thats also the intake for the air going up and out of the roof carrying the CO2 and CO with it from the flame.
It’s a fridge vent. Must be standard placement for the trailer. Also, why does your picture look so photoshopped? Lol
The refrigerator vent’s aerodynamic tapered end is supposed to be pointing in the direction of travel.
Since it’s sideways water was getting blown into the side vents while driving and the DIY wind deflector was intended to remedy that. There will be evidence of the leaks inside.
What are those hexagonal things? I have never seen those before in my 30 years of RVing.
Regardless whether your refrigerator is using AC or Propane the coils at the back still need to be vented. Heat is moved from inside the refrigerator to the outside where it is vented through the roof – cool air enters below and it rises past the coils like a chimney.
