Using 110V

My MH is winterized and the auxiliary and engine batteries have been removed for winter storage.  With no batteries would it harm the inverter/charger, OR anything else, if I plugged the MH into 110V.  Is there anything that I need to know or do before I plug in?? With 110V I could use the electric heater to warm the inside of the MH and use this time to do a few things in the MH while I'm not in a rush getting ready to travel somewhere. 

Referencing my 2007 2350 with Tripp-Lite inverter.  When plugging into 110V without coach batteries, I would make sure the inverter is shut off using the 3 position switch on the inverter itself, and also install rubber boots on the battery cables to insulate them as insurance you won't accidentally short power to ground if the interter was ever accidentally turned on.

You should have 110v throughout the RV with the inverter turned off and no coach batteries.  There is an electro-mechanical switch in a steel box which makes it happen.  In my 2350 with no slide, that switch is located in the front-most dinette bench.  I don't know where it is located on other models.

Ron ... I figured it was safer to ask a question before doing something that I had never done before.  Things can wear out or break down on their own without me doing something stupid to cause a problem ... especially electrical problem.

I should have also mentioned, plugged into 110v, but with the inverter off and the batteries out, you have ONLY 110v opperations.  That means everything that runs off 12V, one being the interior lighting, will not work.
