What does long legged mean (4.56 ratio gears)

[Captain504]

I am purchasing a w900 with a 3406b cat 15speed and 4.56 ratio gears.

Many have said it would be long legged.

What is long legged exactly?
Will truck get up to 65 or 70 mph?
Will I have problems with hills?

I thought it would slower but have no problems climbing or pulling.

Hi.

You've got some responses in your earlier thread here:

4.56 ratio 3406B CAT with 15speed

Can you use a truck with a 4.56 gear ratio and 15 speed 3406B CAT for daily flatbed hauling?
