When it comes to miles per gallon, size isn’t all that matters. Compact,
 aerodynamic and lighter-weight motorized models are more fuel-efficient
 than ever. Towable RVs account for more than two-thirds of RV sales, 
and innovative designs coupled with lightweight, durable building 
materials mean there are many that can be towed by family minivans and 
small to mid-sized SUVs. 
Check out how savvy RVers save on fuel:
Camp
 closer to home. With more than 16,000 campgrounds nationwide, RVers can
 enjoy the outdoor experience whether they travel five miles or 500 
miles.
  
Stay longer in one place. Many RV parks are vacation destinations in 
their own right, offering pools, playgrounds, hiking trails, 
entertainment centers, organized activities, convenience stores and so 
much more.
  
Pack lighter by not topping off fresh water tanks until at the 
campground and by purchasing firewood and other camping materials 
on-site to keep the RV lightweight while traveling. Be sure holding 
tanks are dumped before heading out to further lighten the load.
  
Tune up the engine of your motorhome or tow vehicle, inflate tires 
properly and conduct regular maintenance to maximize fuel efficiency.
Some other facts to keep in mind:
  
Fuel is typically only the fourth largest expense on a road trip, behind lodging, food, vehicle payment and maintenance.
  
Airfares and hotel rates also rise when fuel costs increase and fuel surcharges are added. You can avoid those costs in an RV.
  
Fuel prices would need to more than triple from their current level to 
make RVing more expensive for a family of four than other forms of 
travel.
