End of life indicator

Would Recommend

Five years ago i purchased an identical unit. The end of life beeping sequence prompted me to purchase another. Thus, reinstallation was a breeze, and now I should be good for another five years!

OEM for Airstream

Would Recommend

Replacing a unit in my Airstream. This was an OEM replacement and I didn't have to order it from an RV site. And the cost was the lowest of any site. Just wish it was carried in store. At least the store I needed it in at Kitty Hawk.
