Those Command Hook tapes do not like RV walls. Those walls have a layer or a film of some type of oil and that oil need to be cleaned off. As stated above, clean the spot with rubbing alcohol, let it dry and then apply the Command Hook. I think you'll have much better success! I have hooks on my wall, many of them everywhere, and they have been hanging since we first purchased the camper new. (Ok, I had some failures initially too, that's when I started pre-treating the wall with a good alcohol rub.) That's all you need to do.
Who you are right now is a sum total off all you use to be.
