Mine is connected to 50 amps at home when not on the road. 15 amps would do the job if all I wanted to do is keep the batteries charged and cool down the fridge before a trip. However, every so often the Monty becomes overflow sleeping space so the 50 amps allows use of the A/C in the summer or use of the fireplace in the winter. Plus, in the winter I keep a 750 watt electric heater running to help prevent freezing and to keep the humidity down. Battery checks every 90 days are recommended unless you have a "true" maintenance free battery like the Centennials.
