When my kids were young (5 of them) we took a trip to California from Topeka in our 1968 Pontiac station wagon. During the trip, we had problems as listed below:
1. Oil sender failed and dumped engine oil out in Western New Mexico
2. Engine swallowed a valve (right through the top of the piston) just as we entered the Grand Canyon Park
3. The emergency rebuild caused a blown head gasket on right bank as we were leaving Arizona
4. Stopped at a public beach in Oceanside California and spent the day on the beach. Returned to find a short in a wiring harness had melted everything into one huge glob of copper under the dash.
5. The roadside 're-wire" job left numerous shorts still un found which means power windows no longer worked and the horn honked when I signaled for a turn. I installed a 120 volt light switch in the ignition line to prevent battery melt down when stopped.
6. Blown tire while returning through Nevada (there was a 100 mile stretch of Interstate highway still not finished and no service3s
7. Shorts got into the headlights coming through Colorado causing lights to intermittently dim and go bright. Night travel out of the question now.
8. The Alternator went belly up in Colorado also.
9. Engine running on about 6 cylinders as we pulled back into town.
All of that and we STILL thought the good outweighed the bad :)
