With the
equipment mounted on top of a car, the aerodynamics of
the car are adversely impacted, and fuel economy is
significantly reduced. Even when the equipment is not on
the car, just the bars and mounts reduce fuel mileage
for everyday driving. |
|
With the
equipment mounted behind the car, the equipment rides in
the slipstream of the vehicle, having a minimal impact
on fuel efficiency. For everyday driving, just unhitch
the trailer and
the car's aerodynamics are as originally designed. |

For fuel
economy comparison purposes, below are some general
guidelines based on careful measurements over hundreds
of miles of testing on a wide variety of flat, rolling
and mountain highways. The testing compares a standard
configuration of 3 bikes and a 12 cubic foot cargo box
with a small car as below:
|
Car with no trailer or roof rack |
Car with loaded trailer |
Car without bikes on roof rack |
Car with loaded roof rack |

Versatility:
The standard mounting
bars are adjustable between 36" and 42" spacing, and are
designed to hold virtually all accessory racks offered
by Yakima or Thule. The wide range of accessories by
Yakima, Thule and others enable many
combinations of bicycles, kayaks, canoes, surf boards,
gear boxes, etc. to be mounted on the Dooit™. With optional tongue
lengths up to 8’, the Dooit™ can accommodate two 18’ kayaks
or a single 21’ kayak or canoe. |

Size:
The Dooit™ is scaled to be safely towed by compact and
subcompact cars and other smaller vehicles. The typical
car in this class has a width of 66” – 67”, and the 55”
overall width of the trailer and its load are well
within the wind envelope of the vehicle. Trailers built
for the standard automobile have widths that extend
beyond the sides of this class of vehicle creating a
safety issue. The maximum GVW of 500 pounds (trailer and
load) is well within the design limits of a vehicle’s
axles and its braking systems, yet still allows carrying
a significant amount of equipment. |

Durability:
The tubular steel frame is the strongest
design possible and is many times stronger than needed
for the typical load it will carry. The frame is a solid one-piece welded assembly. The torsion bar suspension
allows loads of varying weights to be smoothly hauled
without requiring adjustment. The powder coat finish is
extremely durable and offers the best possible corrosion
protection. The Dooit™ comes with a five year warranty
on the frame and axle. |
