Thanks for the information. Glad to hear you are getting 8+ mpg. Our current bus is a gas and we are lucky to get 7 with the wind behind us and not running the generator. We are leaning more towards the Diplomat 43DFT ourselves and will pull a Honda Odyssey 4 down.
Can anyone share their experience with the MaxxForce diesel engine? I am familiar with Cummins and somewhat with Caterpillar. We are considering a Monaco or Holiday Rambler that runs the MaxxForce so would like to hear about performance or maintenance issues you may have encountered.
