Bob,

Typically, no, leaving things hooked up won’t hurt anything. In fact, by keeping the power on, you can keep the dehumidifier running and prevent problems.

The biggest issue is the batteries. Typically, you need to check them monthly to see if they need more water. How often do you typically need to add water to your batteries? With very little running and not drawing down the batteries repeatedly, you are likely to be fine. But I would definitely make sure that the batteries are full when you leave them. And be prepared for them to not work when you return.

Another issue could be power surges. Do you have an EMS/surge protector running on your rig? Especially in the summer, you can have problems with electrical supply as everyone is running air conditioners. And storms pose a risk as well.
