Took some time to find some threads about it.
DaveP's sleeper cab with tanker trailer
Another one about Dave's truck
This is an adapted M820 with an old Peterbuilt sleeper, done by member DaveP. Tried to find any more information about it, but these are threads from around and well before 2010.
I was seriously thinking to do something like that here also, but a) I had an M51A2; too short for a sleeper, and b) the European rules on changes to trucks are so strong that it is close to impossible.
Rules here are basically NO to everything, and if Yes, you have to go for a special checking and bring a lot of documentation with you that this is really safe, build according to all rules etc etc.
I was lucky in 2012 with my dump to tractor conversion, both are existing trucks and I did not made serious changes to the frame. Now its even more problematic because the rebuild would be seen as a "new" vehicle and has to follow the rules for new vehicles, like double brake system, emission rules etc. .
