I got mine about 30 years ago she has got a bit bigger now, still comfortable to lie on, when the snoring starts I use the long black pull cord, btw usefull fact it never did snore in the beginning!
Already done this experience in Thailand sitting in the 2nd mans seat,in the locomotive of a passenger train from namtok to kanchanaburi, the 3 occupants of the vehicle survived with slight injuries
After taking my HGV license in Thailand I still dont know if there is any requirement on the number of hours that can be driven!
(Licence can be shown on request)
