Members provided guidance for setting up a new Montana 3915TB that will remain stationary at a lake lot with 50 amp service. The consensus is to leave the battery switch on, as the battery supports high-amperage needs like slide operation, which the converter alone may not handle.

Members provided guidance for setting up a new Montana 3915TB that will remain stationary at a lake lot with 50 amp service. The consensus is to leave the battery switch on, as the battery supports high-amperage needs like slide operation, which the converter alone may not handle. If the RV has a residential refrigerator with an inverter, it’s recommended to keep the inverter on to maintain fridge operation during power outages, especially if the RV is unattended for periods.
There is strong agreement against using slide jacks or supports under the slides, as these can cause damage if the chassis shifts and are unnecessary for long-term extension. One member suggests retracting the slides when not in use to protect them from storms or unexpected events, particularly if using a non-permanent cover. It’s also noted that the battery switch in the convenience center doesn’t cut all power—safety devices like smoke and gas detectors will still draw from the battery. For complete power isolation, a cut-off switch on the battery’s negative post is needed, and a trickle charger is advised if this route is chosen. Winterizing is recommended if the area experiences hard freezes.
