[MBZ] Cummins B5.9 230HP engine

[archer]

I'm thinking about buying a 34' motorhome with the following 
engine/transmission:

Cummins B5.9 230HP @ 2500 RPM, 605 FT. Lb Torque @ 1700 RPM
Turbo Charged Diesel with Allison 6 speed
I seem to remember a discussion about a computer module being mounted on top 
of a Cummins engine where engine heat damaged it.

Any advice, comments, or suggestions about this engine or transmission will 
be appreciated.
