@ Badgoat: Thanks for the link.
There was no travel between Israel and the neighbouring countries until the peace accords with Egypt and then Jordan, but even though the country is small, the reason for no sleeper cabs initially was the extra cost, so that other than some White WC28s which arrived in the early 50s, the trend only started in the 1970s when the first US and European COEs appeared on the scene - these were generally available with the sleeper as a part of the package, so to speak, so people started to demand them and when the first Israeli-assembled Mack Ashdod F700s started rolling out of the factory in 1973 they were all of the sleeper cab variety. The DM could be had with separate sleeper (all IDF ones were fitted with them and some civilian ones) but the one below I posted is an aftermarket job, not sure by whom. There were also a few (US-made) F700 daycabs which had the cab extended by Israeli coachbuilder Dror Sankevich - the DM might have been one he did also...
Here's one (pic: I. Nachman):
Another Israeli special - looks like an F700 but has DM mechanicals. We never had the F900 so this made sense if you wanted a heavy duty COE (Pic: Eyal Ben-Haim)
