Of course... your robot looks to have a lot less cheese holes than a Trinity robot, so maybe it isn't a problem.
We are worried, a little bit. We have 0.125in chassis side plates waiting in the wings if the 0.100in side plates don't quite cut it.

What we did to address the strength concern: with the belly pan mounted the air cylinder mounts are very close to three points of lateral stability: a dead axle, the bent-up part of the belly-pan, and the horizontal part of the belly-pan. They are also not designed to lift the robot completely off of the ground. The four 3/4in cylinders can generate a maximum combined force of ~106lbf, so assuming our robot weighs at least 107lb the center wheels will still be sharing some of the load, especially sideways where the air cylinder mounts are weakest.

Thanks!
