We are looking at a 2013 Holiday Rambler Ambassador 40DFT, 30,000 miles, and it is a beautiful coach, reasonably priced.

We want to change from gas to a DP.

The only problem is the engine, it is a Maxx Force 10 350hp, and I have heard some horror stories about Maxx Force engines.

Some say the problem engines are the higher horsepower engines in tractor-trailers, and the 350 RV engines are OK.

Has anyone owned this engine and what is your opinion?

Thank you in advance for your constructive responses!

If there are no engine parts being made, it is not a good buy at any price.

Yes the 13 is worse than the 10 but both give lots of EGR problems and DPF problems. There’s a reason the price is good. With a complete EGR and DPF delete, it’s a great engine.

This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.
