Recreational-vehicle manufacturers, like carmakers, are hastening to make their products lighter, and more aerodynamic in order to boost their fuel efficiency. (Corbis)

Road trip: RV manufacturers scramble to stretch their mpgs

Lighter, lower recreational vehicles can double gas mileage.

By THE EDITORS OF E MAGAZINE  |  November 14, 2008 edition

Q: My wife and I drive more than 20,000 miles a year in our recreational vehicle (RV), which gets about seven miles to the gallon, but high fuel prices are eating into our nest egg. Are there more fuel-efficient ways to enjoy the RV lifestyle?
– Walter Hendricks, Tampa, Fla.

A:
Major RV manufacturers all report a downturn in sales since the price of fuel started to skyrocket a few years ago. A typical gasoline-fueled RV gets between 5 and 10 miles per gallon, and those who may have bought one to save on lodging and food on their travels are finding that filling ’er up may cost more than hotels and restaurants.

But as elsewhere in the auto and truck industry, some RV manufacturers are scrambling to incorporate gas-saving features and design new models with better mileage and a lower carbon footprint.

According to the website RV.net, several factors contribute to a greener RV. First is reducing weight by using lighter materials and improving structural design. Smaller RV engines also reduce fuel consumption (and weight) – if owners can live with less horsepower. More efficient transmissions, better aerodynamics, and increased non­powered engine cooling round out the suggestions on RV.net.

Some of these features can be found in the new Avanti line of RVs from Indiana-based Damon Motor Coach, which offers a 70 percent or more increase in fuel economy over other large (Class A) RVs.
Damon converts the ultraefficient chassis, engine, and transmission of a leading parcel delivery fleet truck (delivery companies optimize fuel efficiency) into an RV. The Avanti’s chassis also sits lower than that of other RVs, for less wind resistance. Result: 14.5 miles per gallon, twice that of other RVs in its class.

But size isn’t everything. Ontario-based Roadtrek takes stripped-down commercial vans – such as the Chevrolet Express or Dodge Sprinter – and converts them into deluxe, albeit smaller, motor homes with fuel efficiency ranging from 15 to 30 miles per gallon.

Sportsmobile also offers a wide range of converted GM and Ford vans customized as motor homes. Owners of Volkswagen’s popular pop-top Eurovan, discontinued in North America in 2003, reportedly can sell their vans for what they paid for them new, even if they have high mileage, due to surging demand and lack of supply.

Another option for reducing fuel consumption is to put a slide-in camper top onto an existing pick-up truck. The additional weight will decrease fuel efficiency slightly, but you’ll still get much better mileage than with any kind of large RV. Those used to roomier accommodations might opt to tow a “fifth wheel” – a large RV-style trailer with all the amenities – behind a suitable car, pickup, or SUV with a trailer hitch.

But no matter what you do, living on the road is not optimal for your carbon footprint. If the environment is a big concern, giving up the RV – and outfitting your home with energy-efficient appliances – may be a more responsible thing to do.

Please see this essay I wrote for the Huffington Post about this very issue. I think your answer missed a lot of points.

I appreciate your article and am glad to see new options from the RV industry to increase fuel efficiency. I have to disagree strongly with your last paragraph which states that the RV lifestyle is not optimal for ones carbon footprint. We have lived full time in an RV for the past six years, traveling throughout North America. My carbon footprint during that time has been much less that if I had stayed at home. Our RV is 350 square feet compared to a 2000 square foot home. Our water heater is six gallons not 50 and we use about 15 gallons of water per day. Our gas mileage of course is worse but not bad since we pull a 5th wheel. But since we have only one vehicle our total miles drive has actually gone down by more than a third. The fact of the matter is that if you are careful, the RV lifestyle can be more environmentally responsible than others.

Being environmentally sensitive is long overdue on the average American’s radar, but full-time RVers are often THE most environmentally sensitive. We consume in a very small space (unlike Doreen (Hi Doreen!), we travel in a 20′ Class B Roadtrek Van - even smaller), consume very little due to the small living space and we recycle everything possible. On board we have efficient appliances, heat with propane, and seldom air-condition because we move about to comfortable climates. When we were on our year long gallivant around the US, we only turned the air on a couple of times - unlike our larger “stick” house we live in now.

But it isn’t all about the rig, it really is about living one’s life in a responsible and informed way. Having worked hard all our lives, we decided to take a year and travel all across our great country (37,000+ miles, 48 states, 43 national parks) and see just what American’s are all about. It vastly improved our understanding of history, and we now hear the national news with a much different, more knowledgeable ear. If more people would travel and learn, there would be for more understanding of our differences and more tolerance for the way that others live their lives and why.

Hi Carol -
Yes, these are the very same issues I raise in my Huff Post article. As you know, we also took a year off and traveled the country in our converted bus. We have solar panels on the roof, all the appliances (as in most RVs) are energy efficient, if we’re in a town that doesn’t recycle enough, we haul our stuff in our bays until we get to one that does. We use as much water in a week as a “home bound” couple uses in a day and we’re not commuting to work in two cars every day, either. We don’t heat an entire home in the winter, nor cool it in the summer. As I also point out in that article, what better way to appreciate our great country than to actually get to see it. We went from ME to FL to AK, had many adventures and misadventures (fire, flood, armed robbery and an encounter with nudists) while meeting incredible, diverse people and seeing wonderous sights across this great land. All of this gave us more of an appreciation for our environment (yes, especially the nudists) than being “home bound” would have. In this time of so many people needing to downsize, and all of us needing to be more energy efficient, we could do worse than consider the RV life.

The the editors of E Magazine.
“But no matter what you do, living on the road is not optimal for your carbon footprint. If the environment is a big concern, giving up the RV – and outfitting your home with energy-efficient appliances – may be a more responsible thing to do.”

The same thing could be said about living in general. If you want to have the smallest carbon foot print, perhaps you should kill yourself now and avoid the rush.

Hi Alan -

So you are suggesting that living in a 2,000 sq.ft. house with utilities blazing 24/7/365 with full-size (energy efficient) appliances, driving 2 cars up and down the freeway to work across town, etc. is MORE friendly than living in 350 sq. ft. RV with modest-sized, energy efficient appliances/utilities going only when you aren’t in a comfortable climate? For the most part, full timers, don’t move every day - they change by months or seasons in order to optimize the nicest (most energy efficient) climate.

I’d be interested in your stats on that. I only know that we spend far more in our home than we would on the road - and we have a newer, energy efficient home in a mild climate.

Doreen and I both took a year long trip to experience life on the road and in the US, which is different than living full-time on the road. Over 1 million people now do that and most of them that we ran into are pretty environmentally conscious.

No Carol. I actually live in an RV, with my wife, three kids, and two dogs. We been living in it for 8 months due to the housing downturn. It will probably be at least a year before we are able to move into a stick house again.

My point was that it is idiotic for folks like the editors of “E magazine” to point out that one lifestyle is more or less green than the other. If the editors of “E Magazine” really want to reduce their carbon footprint, they should kill themselves, as that is the greenest life style.

Everything else is choices and compromise, and it is wrong to view someones choices though your own circumstances. My grandfather told me not to judge someone until you walked a few miles in their shoes, and that still holds true today.

Green Nerds want to tell us that owning a Suburban is pure evil. Well I got news for Green Nerds. I can’t get two dogs, my wife and my self, and three government mandated child seats into much other than a large SUV, especially if I still need room for a stroller or overnight bag. We barely make due with a minivan but when the kids grow a bit, we are going to have to have a bigger vehicle or stop going to visit our relatives.

This article is right on and the RV industry is coming up with new designs that will help increase gas savings. One device that is gaining some attention is called an HHO Generator. The device breaks down h20 into hydrogen and this hho gas is than pipped into the air intake of your vehicle. I am excited about this new technoligy and hope it finds it way into the RV industry.
