The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree
ramp without lifting any other wheel off the ground. This
distance up the ramp divided by the wheelbase of the
vehicle and multiplied by 1000 is the RTI. The Power
Wagon has an RTI of 655, which means you can articulate
one front wheel 32 inches in the air while the other three
wheels remain in contact with the ground. High Mobility Characteristics
