Just go with the Savage X 4.6 RTR. Great truck, and you can just upgrade as needed. I have the older Savage .25 and havent upgraded much of anything except to a bigger engine and a BP rear differential. Its taken a beating and always comes back for more. Best truck I have owned, bar none.
Truggies are fun, and the best for racing for sure, but for bashing, the Savage is the best IMO.
