I can change a tyre on my 4x4, change an fuel filtre or something similar, but not much more. I know that I need help if something happens.
I can live with that. I need also help when I need a doctor. At home I also need help when something in my flat is broken.
I can`t repair my washing machine, my dishwasher, can not fix my toilet flushing, cannot fix my heater, i cannot fix my TV. In my daily live I regulary need help if something goes wrong.
I drive a new car with much electronic stuff. I know that I have to get the car to a capital, if something is wrong abroad.
When we read some travelblogs, we see too these older less electronical cars who needs to be carried away.
For shure it is good when you know that you can fix some issues by yourself. Too it is helpful when also the guys in the smaller towns are able to repair your vehicle. But it is not required for travelling.
Go out and enjoy.
