Talking shop among RVers, dealers, and manufacturers opens the door to new RV choices, which may lead to new buying decisions. As a result, sometimes that ‘light bulb’ turns on in your head, and you ask yourself, ‘why didn't I think of this sooner?’
We can’t pinpoint the exact reasons behind a final buying decision of a new class A as not all rigs are the same for all RVers. However, one significant decision to always ponder is choosing between gas- or diesel-powered units. It’s not all that difficult, but there are a few aspects to consider before you transfer the payment.

Choosing a Diesel Class A
Sometimes choosing a diesel-powered motorhome just makes sense. When you think about it, driving a class A in the 11 to 12 m (about 35 to 40 ft) range 5,000 km a year with an expansive floor plan, all of your belongings, and a toad on the hitch, the load is a demanding one. This is when you need to seriously consider power and fuel economy.
Whether you choose a front end diesel (FRD) or a diesel pusher, these engines are known to provide much more longevity than its gas counterpart, meaning they will last longer (and when properly maintained and serviced). Since they also crank out optimal low-end torque (since the powerband is in the low rpm range), a diesel-powered rig can better manage heavier loads and take on steep grades easier while climbing to higher elevations. So, if you travel to places like Jasper National Park in the Canadian Rockies, your diesel motorhome will be able to take on the ascending climbs for longer periods without the engine working too hard.

More often than not, diesel fuel costs more than gas per litre, which at first may seem like a larger expense throughout an extended trip. Yet, according to the U.S. Department of Energy, “diesel fuel contains roughly 10 to 15 percent more energy than gasoline and can often run an average of approximately 20 to 35 percent further on 3.7 L (1 gal) of fuel than gasoline engines.”
What this means is even though you’re paying more at the pump upfront, the better fuel economy of a diesel engine means you can travel further with fewer visits to fueling stations. Of course, these figures may vary depending on your load, size of RV, make/model, road conditions, etc. One other benefit is the fact that diesel class A’s commonly have a higher resale value, which is also something to consider if you think you’ll be upgrading (or downgrading) to a newer RV down the road.
Nonetheless, this isn’t to say that a class A diesel is the perfect choice for every RVer. All of these benefits come with a higher purchase price. Plus, even though service and maintenance can be pricey on any motorhome, a diesel class A can be even more so with only specific service centres available. This is an aspect you must always plan for, especially on the road.

Choosing a Gas Class A Motorhome
Choosing a diesel or gas class A should primarily be based on (but not limited to) your budget and how much RVing and how far you travel annually. If you think a diesel class A is worth the investment even though you plan only two or three trips a year with a few weekend getaways in between, then great. If it isn’t, a gas class A is a very viable alternative (or even an ideal first choice) with a variety of benefits.
According to JD Power’s Nadaguides.com, one of the positive aspects of a gas class A is that they run significantly well at higher speeds (and at higher rpm of equal power), which is a definite plus when cruising the major highways and less-crowded byways. Yet, depending on the model, load weight, and brand, the trade-off is they don’t provide as much low-end torque when ascending long, steep grades like a diesel class A, thus causing the engine to work a little harder.

Another benefit of Class A gas motorhomes is you’re provided with all sorts of added convenience during travel. Gas is commonly less expensive than diesel, providing immediate savings during longer trips, and is easily accessible – whereas diesel can sometimes be difficult to find in remote locations. Breakdowns also happen on the road and in the event of engine issues service is readily available (and relatively less expensive) compared to its diesel counterpart.
These are just a few of the common points when deciding between these two power plants for a class A. So, it’s always best to speak with your local dealer as there are a variety of different aspects of design and other driving characteristics. However, some of the deciding factors may be your driving preferences, where your travels take you, and most importantly, your overall budget – whether it’s during the purchase process or when you’re on the road.
