Where is the Spyder's CoG?

I know I'm late to the thread, but here's my two cents.... Look under your Spyder and you will see a flat metal pan about 5" x 24" in the center between the foot boards (I think of it as a keel); it runs from the stabilizer bar to the catalytic converter. The service manual shows a floor jack at the front lifts the front, placed at the rear lifts the rear; your CoG is somewhere in there depending on how the thing is loaded.

If you want a quick & dirty way of determining tongue weight, hook the trailer up, drive your RT in until your spotter sees the suspension on the tow vehicle load up, stop, tie down, go.
