I'm going to have to just simply tinker
find a way to move it with getPos
thingo1 setpos [(GetPos this select 0),(GetPos this select 1),2]; for back of truck
then
~0.1 deleteVehicle thingo1
thingo1 setpos [(GetPos this select 0),(GetPos this select 1),1.8];
Repeat this over and over again til it look like its moving
Maybe even move the truck too!
Make markers and add the object thingo1 again,,,,,
I know this is not tested , but my scripting is horrible , i do everything backwards
But then again sometimes it works,
but dont do your head in over it
edit might work best in a cutsence where you can move the camera,,,,
