detroit vs. cat

[crop_dust]

Hi ya'll. I'm new to the forum and in the researching stage of first
motorhome. A friend in Texas showed me his BB (a mid 70's FC) and I
liked the quality the first minute I looked at it. Anyway, while
searching the net I've seen more Detroits than Cats and I'd just like
to know what ya'll think. We've used 671 and 871's on the farm for
years to irrigate rice and beans and they are noisy and leak oil like
crazy, so how about the 92 series? My wife and I are in our mid 40's
and we are planning on using it in our traveling aircraft maintenance
business and for fun too. We are looking for a driver not a parker.
Not sure how many miles a year but want something what was designed to
go. Thanks in advance for the help.
