Welcome to iRV2.
Glad to have you join us.
Going to have to ask questions.
When you say camper , do you mean , a camper carried in the box of a pick-up truck or some other type of RV ?
What type of RV, year, make and model ? Please
When you say electricity , do you mean you have plugged into power in an RV site and can't get anything in the RV to work ? Lights ? furnace ? electrical outlets?
