We went through this truck and made a handful of changes:
1. Motor flip
2. Electronics relocation
3. Shock tower mounts
4. Shock mods
5. New steering linkage
6. Brass knucks and diff cover.
It remains a chassis -mounted servo though. We have 2 Gatekeepers; one for crawling and one of rock racing, and on the rock racer we did a servo-on-axle mount.
Some time ago we had an Ecto body on it for weight savings ( shown in this photo ) and it was a very good crawler. That said, I missed the personality of the Gatekeeper, so I reinstalled the heavy roll cage. It makes a big difference on steep lines, but I've just learned to deal with it's limitations.
