Update, I didn't mention that the energy control board where it normally shows what amps I am plugged into was completely blank. I got the idea of using the 110 converter and plugging into my normal household outlet and still got nothing. Took the RV into my work and they checked all of the batteries. It seems that the friend where we store the RV for the winter hooked up the battery tender too late and the batteries froze. One battery was broken and the rest were swelled out. They showed a low charge but when a load was applied they all showed a bad battery. We replaced the one battery and in the interest of saving money decided to wait on replacing the other three.
I took the RV home and plugged into the 50A circuit and immediately had power! The energy control panel showed that it was plugged into 50A and everything worked. So at least in my case, yes, a defective battery seemed to prevent me from getting shore power. We will now see if the three batteries will charge and maintain it.
Thanks for all of the replies.
