Take a look at the chassis on our 2014 robot, we use internal belts, and we leave the tube ends open to have access.

Keeping the ends of your tubes open is a plus. If not, consider attaching the front/back tubes & bellypan with bolts for cleaner access. Rivets can be faster to drill out and replace compared to a bolt/nut but having the variable of aluminum shavings flying around your robot in the middle of a crisis repair isn't worth the few seconds in most cases. 3467 ran a Chain in Tube running our elevator last year (the layout was identical to a 6wd setup like this one) and having the ends open made the single repair/adjustment we made to the chains after assembly not as painful. Someone (*cough* me *cough*) accidentally pulled the center output shaft on the practice robot.
