It’s a 4553 model, and the selling dealer say it’s a 500hp. All the brochures and information I can find says it’s 600hp. Anyone know for sure? I have the vin if that helps.

As mentioned above, the X12 will be around 450 - 500 hp, and the X15 will be in the 600-605 hp range. As far as I recall, the X15 may not have been available in the MADPs, so it may be an X12. Either one of those engines are fantastic, but the X15 is in a class of its own IMHO.

We aren't in a race anyway, so if you are comfortable with it while cruising and hitting some reasonable hills, it should work.

It doesn't really matter, both will work fine. 2014 American Eagle diplomatdon • View posts Blaine, WA Full Member Joined: 08/31/2015 View Profile Good Sam RV Club Member Offline Posted: 11/21/22 08:04pm Link  |  Quote  |  Print  |  Notify Moderator Just look at the engine. It will be marked probably on the timing cover, ISM or ISX. Problem solved.
