There's a lot of Navistar Engines in use out there, and getting service and parts is not a problem

[Opinion About Motorhome Specialities In Texas]

Henry P,

Really sorry to hear of your troubles with Monaco. We have nothing but good to say about Monaco and the way they have taken care of us-- even after ASV took over last year.

We stopped at Coburg Factory repair center on our way home this spring and they went above and beyond to take care of our problems.

Add a cup or two of Calgon Water Softner along with the Pinesol and it helps even more. Especially if your in an area that has hard water

[Comments Good/Bad on Monaco Diplomat 43DFT]

We have a 2013 Diplomat 43dft. Our MAxxforce 10 with 405hp and 1,250 ft/lbs of torgue has just over 13,000 miles on it. The only problem we have had so far is a faulty cam position timing sensor. Otherwise this engine has performed and worked as expected. When I did a back to back test drive compared to a Newmar with the 8.9 ISL Cummins, I honestly couldn't say one preformed better than the other.

So far we are really happy with our coach and have lived in it fulltime for over a year. We probably had the normal amount of new coach problems. Mainly small items that we're easily corrected.
