By our measurements it is about 29inches long while inclined and I'm just double checking that that would be a legal measurement.

The rhino tracks make me asking the frame perimeter interesting, as the frame elevation changes depending on where you're looking. To help determine your frame perimeter, think about what a bid to contain the robot would look like. The walls would be perpendicular to the floor, and pressed right up against the front, back, and sides of the robot. That box then defines the frame perimeter.
Please keep in mind the bumper mounting rules. Specifically 8" from each corner of the robot (including in front/behind the treads!), With the 1/2" of support at each end of the bumper. Depending on what your doing with your design for supporting the bumper, you may need to add more frame material to get everything properly supported - and that may change your frame perimeter!
Please feel free to PM me if you need more help with this. You're located a little less than an hour from my house, and I will be one of the LRI's in attendance in Duluth while you compete
