I'd like to multi quote several of the above folks who decry the "Thai bashing"...suffice it to say, I have worked EXTENSIVELY with the RTA, and quite a a bit with the Thai Marines.
I was a Field Service Rep for AM General for many years.. AMG manufactures the HMMWV (Humvee) military truck. Those trucks are over the world, and I was based in Thailand to help with their 2,000 trucks. Taiwan has 4,000 or 5,000. US Marines on Okinawa + US Army in Korea.
The RTA conduct maintenance like a bunch of 16 year old kids. Drive it till it breaks.
I have seen steering linkage tied together with a broken fan belt! Peanut butter in the brake Master Cylinder (brakes failed, anyone, anyone ever heard that???).
They were sending 72 trucks to Sudan on a "Peacekeeping Mission" to help the UN...asked me to inspect the 35 year old trucks (this was years ago).
I came back with a folder about 4 inches thick, and gave it to a Full Bird Colonel. and identified 38 trucks I would be TERRIFIED to even drive into the workbay to try and fix.
In the US Army, we called it a DEADLINE issue = UNSAFE to operate.
They just grinned at me and sent them off to Sudan.
Oh they DID paint them white with UN markings, re-did the upholstery on the seats, and put new, shiny tires on them.
