Default Pro and Cons with regards to DD 8V92 vs Series 60 vs Cummins in Motorcoach?

While considering some different higher end luxury coaches or motorcoaches and thinking about the different engines available, why did many of you choose the motorcoach that you have? Was the engine a major consideration? Do you have the engine of choice? Just trying to make more of an informed decision here while in our search and hope that we can get a somewhat unbiased answer here. Thank you very much for your help in advance!

Hi Donald and Diane and ! I don't think I greeted you since you have been hanging around. You have a good question and I think you can get some biased and non-biased opinions around here and you will have to be the one to sort through the rubble. You will find some folks that may love one engine over the other while being in disagreement with another person having had or enjoyed a great experience with the same engine, while another person may have gotten screwed over on a bad engine in a coach when they originally purchased it. To be honest all those engines are great depending on what you are after.

Your 8V92 as long as it is a Silver Series is a pretty descent engine. Silvers don't have the leak problems and have the better component options. From talking with several mechanics over the years the DDEC 4 is the best choice of this engine. Engines with computers normally last a lot longer then those without. Just better engine management. Parts are not all that bad to come by for this engine, the biggest problem is there are fewer mechanics that know the engine then there was 10 years ago and in the future that number will surely continue to diminish.

Series 60 Engine is my first choice in a coach engine and this is the most commonly found engine in the bus fleets, in fact thousands of older still on the road Greyhounds and other tour buses have been converted from the two-stroke engines to the Series 60's. A lot of that could be due to emissions and fuel savings. A half mile to a mile per gallon in a fleet means huge savings. This engine is a great choice and tons of parts and guys that know how to work on them. Two less cylinders to worry about.

Cummins has made several great engines and have an easier time meeting emissions standards than probably any other. Parts and service are not all that bad either. Depending on what coach you are considering, you won't find many Cummins in the high end luxury coaches unless it's a very late model Newell or the last of the Wanderlodges. Of course there are a lot of common chassis built motohomes that come with them.

There are a couple of other engines choices out there you didn't mention like CAT, International, Volvo and Mercedes. CAT's are the most expensive in my book for parts and repairs, besides they have abandoned the RV or highway industry and are currently sticking to off-road only. For the time being anyway, with them mainly having an issue do to not wanting to deal with the emission standards. They are reconsidering the market again. Newell Coach Factory engineers have been talking to them as are other RV chassis manufactures. Volvo is that standard in the Newer Prevost Car motorcoaches, the main reason being that Volvo now owns Prevost.

We do have a few other straight shooters hanging around here that will surely chime in and share their opinions.

Ken, thank you for the great information and Jon that link really gets one thinking. Sounds like some great options one can consider depending of course which direction we might go. What year Newell's and Wanderlodges have the series 60 engines?

If I decide to upgrade my first choice is Series 60 when you compare power and fuel economy.

Newell's came out with Series 60 in about the middle of the '95 production year and the factory ran them up until 2006 at which time they went to the Caterpillar engine. They are currently running the Cummins engine.

From my knowledge which is more limited on Wanderlodge, they too started using the Series 60 in the '95 model year and ran it up til at least 2003 at which time they offered Caterpillar and Cummins. Wanderlodge went bankrupt for I believe the second time in 2009. What a shame as they are a great product too. In fact there are probably three times as many Wanderlodges as there are Newell's.

Anything else just ask.

Donald and Diane: welcome to the site. The brand of engine made absolutely no difference in my selection of coach. I chose the coach I thought was best and it came with the engine it came with. I trusted that all the major diesel engine manufacturers supply good engines for the high end coaches. A decade later I still believe that. Regardless of brand you want to get any prospective engine checked out by qualified mechanics - something I failed to do with my 6V92T and it ended up setting me back several thousand dollars for an in-frame overhaul.

My advice: find a coach you both love, have the mechanicals checked out by an expert and then go forth and travel.
