Hey, that storage will be quite beneficial. Just 2 weeks ago I installed the 52 on my Burgy. Probably only two cautions I would suggest to watch for...be reasonably careful when pulling off the upper and lower back covers, and the instructions at least the way I interpreted them did not exactly show that those 3 heavy metal spacers actually are designed to be put through the plastic top cover....after a little deduction....I finally figured that aspect out. The X marks on the underside of the top cover are right on the money. Drill the holes centered right on the X, and you shouldn't have any problem. And then, of course, be reasonably careful when re-installing the top/bottom covers. With regard to the backrest, I may look into a re-design made possibly by my brother(he just doesn't know it yet!). But, by trade, he's an upholsterer...at first glance, the back rest is a somewhat hard rubber....but my wife and I will check it out come Spring....to see if she's going to be comfortable on a 2-3 hour ride. Finally, don't be bummed out if you should break or snap off one of those plastic clips....they're quite cheap to replace, and should be replaced because the overall plastic covers just won't quite fit together without those clips. But our topbox looks great, having purchased the monokey setup....a bit pricey, but in the long run....worth it.
Good luck!
