The GVWR for a '94 Wrangler is 4300 lbs.  That has about 800 lbs of passengers included, so call the empty curb weight 3500 lbs.  Weight distro is about 60/40, so the front axle load is approximately 2100 lbs.  Looks like we put about 1100 lbs on the CubeSat.

The four corner blocks of the side rails dug firmly into the wood blocks...

You can even see footprint of the kill switch.

But none of the internal boards, panels or rails were damaged
