I have been considering one of the DX3 models and it appears most of the dealers are stocking the Cummins 8.3ltr engine models, instead of the 6.7ltr engine. Several of the dealers have some nice photos of the rigs, better than the Dynamax site IMHO. Here is a New Jersey dealer, Dillons. See that Motor Home Specialist RV in Texas has them advertised at 25% off the MSRP. Works out to be just over $204,000 for a somewhat loaded model.
