I'm also one of those!! The RV stays fully stocked with everything we could need for at least two weeks (clothes, dry goods, emergency rations, canned foods, etc) except the frozen and cold foods. We cannot keep the rig at home (thanks to local city regulations) so for a planned trip it is at home o'night to cool the fridge / freezer and next morning load the cold stuff and GO!!
There is ONE exception...I keep a list in priority order of the things we need to take from home if it is a panic departure - SHTF, Katrina, etc. You too should have such a list and hope you never need it! Important papers and other stuff from the safe (cash), prescription meds and their papers, etc. Make-up your own list and then see how long it will take to 'get out'a Dodge'! Anything after 30 minutes gets left behind!! Think about it and (in the words of my old Scoutmaster): "Be Prepared"!!
