Preparing an RV to be left unattended while traveling by air

i wanted to minimize all other power usage to prevent my batteries from going dead so i turned off my refrigerator freezer and i emptied out from there all anything that would spoil

i decided not to because if anybody really got curious i think it'd be better for them to be able to look inside and see that there's nothing terribly valuable in there

i'm going to go on some more cruises over the next few years and i think i'm probably going to do this same thing where i just simply park my motorhome in a parking lot
