Not sure if this is on the right forum.
I'm a new guy but I've followed ETS for years.  I'm fairly confident on the standard basics of being prepared but my situation is a bit unusual - I use a manual wheelchair - and I'd like your input.
My wife is able-bodied but we're not together all the time (part of the reason we've been married 25 years *smiles*) - she supports my preparedness obsession.  I work in a very large public building (w/ attached parking deck) in an urban setting.  I commute 10 miles each way.  Winter weather in NE Ohio sucks.  I drive a fair amount (east coast a few times a year, vacations, etc).
Since I'm not very mobile except on hard flat surfaces, my van (no lift) is my BOB.  I have gear and supplies to last until the cavalry arrives.  I have 2 cell phones (different networks), a CB, and an FRS.  If I'm home I'll opt to bug-in unless forced out.  I take no meds and need no special accomodations beyond the completely obvious.
Basically I rely on good communication, always having my vehicle nearby, and the ability to wait it out.  Any suggestions?
