This is based off a British Fuel tanker
I used the following images as guidance:

DISCLAIMER:
This fuel tanker unfortunately does not actually refuel planes. However, if this option is added in the future, I will add the required blocks and so forth to allow it to refuel.

Functions:
- Suspension between the tanker wagon and cabin.
- Lights (next section says how to activate them all)
- A moving steering wheel in the cabin
- A cabin modelled on real colours
- A tanker (not modelled on real colours as the patterns required to this would make this project alot more difficult)

Light controls:
- 1 for left indicator (front + back)
- 2 for right indicator (front + back)
- 3 for orange warning lights (used to let aircraft know the tanker is there) (attached to both sides of the tanker itself)
- 8 for headlights (on by default) (Front + back)

Driving controls:
- W to go forwards
- S to go backwards
- A to turn left
- D to turn right
- B or Ctrl to brake (note it is very sensitive)

I hope you enjoy this model, I am aware that the front wheels are a bit too set back but I feel as if this adds a bit of pleasant dorkiness to the design.

Comment your opinions on the model and if you like it give it a thumbs up! Cheers
