Best setup for a "crawler" savage?

[Nixpus]

Hi guys,

Since I almost bought a new truck in spareparts when I converted to a Savage XL I might as well make something out of the old roller.

Id like to turn it in to a crawler wanna bee:

• The diffs should be locked...
• I guess the suspension should be super soft?
• Im thinking the terra pins could be an ok tyre for this purpose?
• Increasing the wheelbase could also be considered.
• Almost any motor should be able to fit this purpose as it will be geared for pretty low speeds. or?
• What else?
