  1. Why Buy A Diesel Coach RV
    The Diesel RV Buying Guide

  2. More Torque Equals Less Strain

    One of the main advantages of a diesel engine is torque. A diesel engine is working at its best with the maximum horsepower and torque at a lower RPM than a gas engine. And of course more torque means more power to get over those hills. Also the torque is vital for more efficient towing which we find almost all of our buyers plan on doing. All this also leads to the fact that a diesel engine is not working as hard to pull the hills and tow the weight. Therefore it is easier on the engine and a better mile per gallon average is obtained over a gas engine (more on this later). Something else to consider is longevity, for the same reason commercial interstate trucks use diesel engines. They simply are capable of going hundreds of thousands of miles further than a gas engine.

    Diesel Chassis Last Longer

    Another major advantage of a diesel powered RV is the chassis. Diesel chassis are typically much better built and have much higher weight and towing capacities than there gas counterparts. The diesel chassis also has air ride suspensions which greatly improves the overall ride. In addition they also typically have some sort of engine or transmission brake retarder. And from our experience there is nothing better to assist in stopping, and efficient braking on a decline than a diesel engine with some sort of retarder system. All of this also adds up to a much more safe and solid ride in our opinion.

    Diesel Coaches Retain Resale Value

    We also find that diesel coaches also retain a higher percent of there original value than a gas powered RV. Another plus is the fact that the NADA guide which is a trusted resource for determining the value of a pre-owned RV deducts from the value of a gas RV as more miles are driven. They have specifically written instructions when determining the value of a diesel RV that the mileage is not considered a factor. So certainly if you plan on putting many miles on your RV you would be better of with a diesel.

    Diesel Coaches and Fuel Mileage

    Diesel fuel has a higher energy density than gasoline. One gallon of diesel contains approximately 147,000 BTUs of energy, while a gallon of gasoline only has 125,000 BTUs. This means it takes more gasoline to equal the power output of diesel, making diesel engines more efficient per gallon of fuel burned. Also, because diesel engines use the more efficient direct fuel-injection method (fuel injected directly into cylinder) compared to the port fuel-injection setup in gas engines where gas is mixed with incoming air in the intake manifold, the diesel system has little wasted or unburned fuel. Of course variations exist of many kinds but from our experience with moving RVS all over the country for the past 15 Years we find that the average MPG of a diesel RV is 7.5 and that of a gas powered RV is 5.5.
