Down to zero

We sold the malfunctioning Honda (bottom rusting off) to pay our midwife bill. We borrowed the van from my parents until it broke down (unknown, while they were driving it). We borrowed the Lumina until it broke down in Shell Rock (alternator, we were driving it). We came close to a break down in Wisconsin with it previously. Yesterday on my way to Cedar Rapids, I had to pull the blazer over and quickly get my son out of the back seat as smoke came billowing out from under the hood. The man behind me called the local fire department. The second person behind me put Link and the car seat in the backseat with her two occupied car seats and brought us to the neighboring house where we sat for a while why my car was towed and Amber came to pick me up. We are now down to zero. It sort of makes you feel like a bad a bad car caretaker, but I remind myself that I bought a used 1993 Tempo in 1996 and I had no problems with the car until 2004. (Minus the broken electronic seat belt from when a deer came plowing into the side of my car.)
We are thinking of either buying a conversion van or a truck with a extended cab (and later an rv insert for the back). We are itching to travel again and the timing feels right. But our vehicles are letting us know they are not the right cars for the job.
