Thanks to everyone for their replies!! After much thought I'm not going to plug in at all. In fact, I'm strongly considering moving the RV to another storage unit. I have to find out some information from the owner first. Here's the story... I live in a small country community. The place where I have the unit stored is a mini storage place with a few parking pads for a couple of RVs. We previously talked to the owner about building covers. He said he would consider it. His close friend had also been asking so he built a storage bay for two RVs a few weeks ago. He said he was going to run a line to it so we could trickle charge the batteries. So as of last week, my RV is currently parked under the new carport cover next to his friend's RV. Upon closer inspection, I realized the outlet isn't a GFCI. I think it should be since it's outside and is susceptible to moisture among other variables. I am also unsure of his insurance on the structure. All of this mixed with it being a VERY VERY tight squeeze getting under the carport to begin with is leaning me towards finding another place to store the RV. I do however like the closeness to my house and the security at the current location. I'm going to talk to the owner before making my decision but my gut says go elsewhere.
What would you do? Any thoughts?
