the rock crawler (6+:1 low ??) SM 465 or 420 should be able to handle it but don't speed shift. they are pretty bullit proof. 420 is hard to find parts for. How much can the T5 handle??
Gooday

small wheel moves by fire and rod,
big wheel fires by the grace of god,
everytime that wheel turns round,
bound to cover just a little more ground.
