While I love the fact that I can take off the back hatch on my Puma to get at batteries and such. Its not the easiest thing to put back on. Granted its really not hard either. However, if one of the pegs were slightly longer than the other, you would only have to align one of them at a time rather than both at the same time as is. Just a thought, probably one that has already been though of. Or if someone has a fool proof way of putting it back on with your eyes closed..LOL.. lets hear it.
