I'm deciding between a 2012 Monaco Knight 40'PDQ Quad Slide with a MaxxForce 10-350 HP Allison 6 Speed Roadmaster Raised Rail Chassis for $149K(mint condition)or a 2006 AC Eagle 42R Tag with 525 Cat for $168K. I'm not familiar with the reputation of Monaco but from what i'm understanding this motor is a "Regen" and has known cooling problems. Obviously the 2006 is 6 Years older (did i mention the 525 Cat?)but again I'm reaching out for opinions on personal experience or even more issues to be advised of since i have not read read all that is on the web over the last 4 months in regards to these 2 Coaches. Thanks in advance!

I assume the maxx force engine is the same basic engine that International used in their over the road trucks, it would not meet 2010 emission standards and they quit using it by otder of a federal judge. if possible get the warranty repair records and do a google search on this engine.

If you are going back to 2006, look at Monaco's from that time frame. The top-of-the-line Signatures, Executives and Dynasty's were beautiful and would be DPF free. The more you go up the line, the bigger the engine.Personally, I would go with an older Monaco vs. the older American Coach if you are comparing apples to apples...... I like Cummins better than CAT. It might be that a Signature could have a Detroit Diesel installed (plus).I'm going to say it, I would not want a Maxx-Force engine. Why would you want that when you can have a tried and true Cummins.MM.

Cat is the best bet by far but go for the floor plan you like best thats more importain than a moter youll never wearout

Between those two I would go with the Eagle.

You don't mention the mileage/ condition of the AC but that would be my choice unless there was some glaring problem. The Monoco is a post Navistar International year and I have read some negatives about that (otherwise Monoco is an excellent coach).

You will hear negatives about any coach. Seems most folks are pretty happy with there Navistar International coaches. I know after 3-1/2 years and 25k miles of fulltime use in ours, we really haven't had all that many problems to deal with.

Although I too like the AC Eagles

Another positive for the Eagle is the great tech support system from American Coach. The folks at the 800# will even walk you through a problem until it's fixed.

I assure you that the 2006 American Eagle has a one piece fiberglass roof. We had a 2005 Revolution LE that had a fiberglass roof, so I am sure the Eagle did also. I believe that the Eagle had a fiberglass roof back before 2000. It might have always had the fiberglass roof when it came out in 1992 or 1993.

As an owner of a 2012 Maxxforce 10 I can tell you there are loads of untrue comments made by non-owners. The 10 series has very few issues, no more than any other engines of the same time period. The larger 13+ engines have the problem EGR system and are no longer in production. I am at 36,000 miles and have yet to do a forced regen. The key is to have the ECM updates done, run it hard and limit idling.

Eagle all the way, over most anything for me. One of my dream coaches.

Maybe This will help. Looks like one piece fiberglass.
