Diesel or Gas Class A, That's the question.

Modern diesel engines in a large vehicle are usually more powerful, perform better on the road, are more economical to own and run, and are very reliable. There is a reason they are in every over-the-road truck. Gas engines are powerful up to a point so are a good match to smaller Class-A motorhomes, are equally reliable, can cost a little less to maintain over the short term but long term (say over 200K miles) the diesel will catch up, and are cheaper to buy. So each has it's benefits. The key will be simply what's in the motorhome you decide to buy. A larger 40 or 45 foot model will have a big diesel engine. A smaller 30 foot model will probably have a gas engine. Mid-sized you usually can find either. Modern diesel engines are both suffering and benefiting from pollution controls. They need DEF, they are far more complex and electronically controlled with all the attendant sensors and computers, and that can mean higher repair costs if something goes wrong. The upside is they are more efficient than ever before, and can get astounding fuel mileage. At the end of the day, what matters is the view out the front window!
