RE: getting back into it--recommend me a truck
Monster GT or Savage
My only complaint about the Sav is that it's a pain to work on, but it's built like a tank.
The MGT is a great all-around truck.
I have a Marder, but I wouldn't recommend a 1/5 or 1/6 scale. 1/8s are a lot more fun.
The Mammoth is great too, but it's a speed demon...not built so much for torque.
