We had a problem the wall clock would fall down during transit. They wall clock that came with the RV and ones purchased had problems with reliability. The first clock lasted 2 years but kept falling down during transit. The second one I was able to keep on the wall but it failed in 2 years. I finally purchased a Atomic Clock from COSTCO. Its made by LaCrosse and has the ability to check WWV and/or WWVH for the correct time. It also uses 3 screw heads to fasten it to the wall at the top. and velcro at the bottom. It keep much better time than the last 2 clocks and it stays on the wall during transit. It remains to be seen if the unit lasts over 2 years. If you want a clock this is a regular maintenance item.
