Same experience here, but I have removed my front panel several times just to make sure I could remember how.I'm on 5 months, and no squeaks. I've heard some folks having squeaks coming from not putting the tops on correctly. I have used my front power almost daily, and no issues, no squeaks, no leaks.
Also, if you don't re-install them correctly you WILL know. When you look at the roof from the outside it will be obvious if they aren't locked in properly.
