This year, its easy to have a good drivetrain (kit chassis, kit wheels, IFI wheels, AndyMarks), and a good capper (the arm is simple, and doesn't have to be excessively reinforced, because the tube weighs .9 pounds). The tricky part is choosing the right "gripper" to handle the tubes, and then deciding whether to add on a ramp, or two, for 4 inches, or for twelve.

Depending on your team's ability to execute, many things are feasible. Just take them on one at a time in the design phase, and make the choice, after looking at the added complexity in the design, what to do.
