Seeking indoor storage between NJ and SC for under $100/mo

[SCOTTinNJ]

I'm looking ahead to this winter when I may need to store my trailer for a few months.



Does anyone know of a secure storage facility anywhere between NJ and SC that is:



a) indoors; and
b) less than about $100 per month?


I've found a few that are more expensive but they tend to offer services I don't need such as washing, repairs, dump stations, etc.



If I can't find anything for less I'll store the trailer underground in the caves near Pittsburgh. I've stored there before and was very pleased. Just was looking for something more south/east.



Thank you.
