RE: Toughest truck????What breaks?
For toughness there's no question - get a Savage X SS or the new 4.6X RTR is you don't want a kit(I recommend the kit though as it's fun to build, you can put in better electronics, even sell the engine and put in what you want, and there are some other advantages too... That said, this new 4.6X RTR is surely the best RTR Savage ever.. Performance-wise I don't think there's much of a difference from the X SS kit..)
The MGT has a rep here in Germany anyway for being very tough too...
And BTW, my LST2 is proving to be much tougher than I expected...
But if you're only focussing on toughness, then defo Savage.
