Yes, More potential energy yES
The potential energy will double too.
Is it changing from kinetic energy to potential energy

Potential energy is "stored energy" because of its position in space. For example, a car parked at the top of a hill, or the water behind a dam.

I'm assuming you mean the big rigs, 18 wheelers. They usually consume diesel fuel. Also, when they are moving they possess Kinetic Energy and while parked on a hill they possess Potential Energy.
Any object which is moving from a lower level to a higher level is converting kenetic energy (ie climbing a set of stairs for example) to potential energy. A car which has been parked at the top of a hill has used kenetic enegry to get up there and has potential to roll down to the bottom of the hill if the brake is released.
A rock on top of a hill has potential energy, not kinetic energy. If it starts rolling down the hill then the potential energy transforms to kinetic energy.
the object has a potential energy relative to , for example, the bottom of the hill, or the bottom of the slide.
