Page "Recreational vehicle" Paragraph 87

; Hub & Spoke: A travel pattern of many RVers that reduces their overall fuel expenses and carbon footprint, as well as the frequency ( and bother ) of breaking camp.

RVers will drive / tow their RV from, for example, Phoenix, AZ, to Tucson, AZ, 115 miles ( 186 km ) away.

They will then spend a week or two exploring Southern Arizona using their tow vehicle or towed vehicle, leaving the heavy RV parked in their campground.

The " hub " is the campground, the " spokes " are the routes fanning out from their campground that they take on their various day-trips.

Some RVers extend the hub & spoke pattern one more level by carrying bicycles, Segways, or other low-carbon conveyances on their day-trip vehicle to tour / explore their various day-trip destinations.

Again using the above example, a pair of full or part-time RVers might break camp and move the 115 miles ( 185 km ) between Phoenix and Tucson, averaging 8. 5 mpg ( 3. 6 kpl ); but then travel 300 miles ( 482 km ) in the ensuing fortnight in their towed car, a hybrid, averaging 40 mpg ( 17 kpl ).

Add another 50 miles ( 80 km ) together on their two Segways, at the equivalent of 275 mpg ( 117 kpl ) each, and the overall fuel economy for the leg of their trip involving Tucson works out to 21. 7 mpg ( 9. 2 kpl ) overall.
