How wide is the frame at that point? Maybe you could just get some 2x4 tube and cut it to fit the contour of the underside of the frame in that area. You would effectively increase the depth and strength. Just be sure not to make too many abrupt joints. Maybe add some 3/16 or even 1/8 flat bar to the bottom, a fish plate of sorts, extending a few inches beyond the ends of the added metal. Taper the ends of the flat bar so you don't have an abrupt joint that would create a stress concentration. Let me see if I can find some pictures of some fish plates to show you what I mean. Right now, most of my Jeeps would fit under a trooper. Out of three Jeeps, not one runs. But then again, neither of my Troopers are doing well either <img src="/forums/images/graemlins/shiner.gif" alt="" />
