DP going up and down mountains

Thank you to everyone for the positive responses and the condolences from those regarding the negative comments. Even though I have owned the RV for soon to be 4th years assume that I have been driving it that long as fir the first 3rd years the a RV has been in and out of shops as the RV should never been safetied but I relied on a very good friend who owns his own construction company and drives diesel trucks that the RV was okay. Very frustrating but I have stuck with it through knowledge in reading this site. I have never driven a standard so unaware. I have only been on 6 trips in the last 4 years. So to those who have concerns about myself as a driver....dont be because at least I am admitting I dont know something. ..am willing to ask...and then do more research to put into action. So....be kind those of you who are perfectionists with their knowledge.
