1) Savage
2) Revo 3.3 with RPM arms, side pipe and wing
3) LST* with RPM arms and roll bar
The savage has diff/center axle issues. Proper shimming and alloy gear box's help the diffs, center axles are an ongoing battle...
Revo has weak arms and the roll bar flex's which is prone to crushing the engine. A better roll bar and wing helps combat that.
LST has two speed issues, weak arms and stupid sized tires that cause things to break due to the extra mass and leverage.
Fix all the bugs on any of them and they are all good trucks for a basher. I have all 3.
Never seen an MGT in person. Looks like a well built rig. From what I've read, they require RPM arms and aftermarket hinge pin braces.
