Tell me where the structural integrity is-

[AC7880]

My 0nly 2 diesels have been a 83 FC35 Cat 3208 225 HP, and my turned up mechanical Turbo Cummins 8.3 in my 94 BMC 37'.

What years did the EGR kick in on Bluebird? 2004 as below? What effect on MPG, HP, and TQ, heating/cooling from EGR?



"I am with you there Steve, and from my personal perspective I would not consider buying a new coach at all. After having had a fleet of new trucks with DPF's and DEF, I have learned that all of these new emissions systems are problematic. It seems that 9 issues out of 10 are related to the emissions systems. FWIW, I have no issues with the 2004 emissions regs that require EGR only, and that regulation extends to include 2007 model year engines. For me that is the newest coach that I would ever consider owning. "

Also, what are the opinions on the ISL in the M380 VS the ISM in the LX coaches?

Would you consider one engine inherently "better" than the other, or similar given the different application of coach weight? Would you think MPG of the M380 and the LX would be similar given the different rear axle ratios and higher TQ of the LX? In other words, would the LX ISM overcome the greater weight with the higher TQ and axle ratio?

My "guess" is the LX will be around 1 mpg less than the M380. The M380 scares me a bit with the limited CCC, availability of front end components (ball joints), and the head gasket issues affecting some of them.
