No special reason and not even sure what Cummins did after that to comply and stay on the road, but definitely don't want to be buying DEF for now and probably never will at my age.
Beginning in 2007, Cummins went with the diesel particulate filter (DPF) to clean up emissions. I don't think they added DEF until about 2010?
That's interesting and really didn't know what they did to stay in the highway business.
I think CAT spent around a 1/2 billion on ACERT technogially, before saying goodbye and after the Gov. stepped things up a bit in the emission control dept.
The DPF is part of the system used to clean up exhaust. Cummins and the rest went to an EGR system. CAT tried and couldn't and is why they went out of on road diesel. Here is a little article about EGR technology, go about half way down for diesel. You will see it dumps junk back in the engine which is bad for it.
Diesel engine makers went to SCR(selective catalytic reduction) around 2011 or 2012 depending on credits they had to the government. There has not been as much trouble with the engines using this technology verses the EGR. SCR does use DEF, you put some in a tank, usually runs about a gallon to 1000 miles. This tells about SCR about 1/2 down for diesel.
I would say do a little reading on EGR technology verses SCR technology in diesels. Trucking industry had a lot of issues with EGR. Here is a good article on problems pre-SCR.
It's my understanding that the CAT pre 07 engine only uses ACERT technology, which is not the same as and actually an alternative to EGR and one of the reasons I went for it, so not sure if you're including the older CAT's here, like my 06, or not............
ACERT

I think the Fleetwood Revolution series in the '07-'08 time frame is a close contender to the American Eagle. Again I think the Tiffin Phaeton is a step down. Tiffin did not make a 40' Bus 1.5 bath in'07-'08 which would be somewhat comparable to the Revolution and Eagle.

Well I did buy a 7 yo Infinity and sold it when it was 15 yo. So maybe that's the kind of guy I am.
I probably won't finance unless my advisor tells me to, so probably won't have to worry about being older than 10 years. Thanks to Isaac about the info concerning the price drop at 12 years, all good info. And Mr Mark, good info too, thanks.
I'm kind of learning toward a '08 or '09 Revolution. Not a lot of the E models around, but they are there. A newer '11 Tiffin Phaeton with the rear bath will be easier to find but will cost 20-40k more.
I want to sell my boat first, but if one of the above at the right price came along, well ......
