Hi Rick,
Welcome to the forum.
I'd propose to exchange the standard motor by a better one. The standard motor is too fast. In addition you should spend a bit of money for a ballring set. It will make the truck run smoother and it extends the time you can drive with one battery.
My first truck also had the gear box, but in the meantime Ll my truck do have gearbox drives from Servonaut like the
GM32U370. It's a real cool and realistic driving.
Have a lot of fun with your truck and trailer
