On truck accessories

Last night I was riding in a van going through roads in relatively rural (outside Manila but not in the jungle) The Philippines. I was surprised that we saw so many jeepneys still operating at 3 o'clock in the morning. I wasn't surprised to see a fair number of trucks. I am assume that whether they use many truck accessories, they had to go a long distance in a short time. This of course is common, and it can't be an easy job in The Philippines where driving conditions are difficult even in the developed areas. I don't know how they get items to the real jungle areas.
