These diesels are essentially the same ones that all the OTR trucks are running for 500K+ miles. The difference is probably maintenance practices.
Yes, but also in RVs they spec higher HP than their MDT counterparts (most box trucks still only have 200-240 hp). Another big one is cooling. Engine makes have little control over how RV makers package their engines and manage airflow, radiator stacking etc. Finally some engine changes are made to allow for smaller packaging, such as smaller filters, combing filters and separators etc.
There are not a lot of REAR engine diesel over the road trucks. :B
There are, however, a huge number of rear engine diesel commercial passenger/tour busses, and have been for many decades...
