The only time that my tonneau cover won't open, is after a quick freeze after it was opened during the time it was wet. Once it thaws out it runs fine.
The only time I get water leaking in, is after running it through the car wash, it leaks slightly at the back, where the cover edge meets the tail gate.
This is due to the seal on the edge being slightly worn and nicked.
I try not to open and close it too much during the winter, in order to save the drive motor.
My truck was equipped with this tonneau when I purchased it, so I can not answer your other two questions. I can tell you that it all unbolts/ unplugs from the box if required.
From their website, I can see that the closest dealer to us is located in Burlington.
Four other things to mention, one small looney sized spot of the black cover coating has chipped off, and sometimes I have found the tonneau open once or twice, after the remote has been in my pocket while I'm moving around working on something. I tend to keep the truck and tonneau remotes/ key chain in my tool box these days. It also has a lock mode (hmm.. I wonder if that would help keep it from opening by mistake, but that button could get pushed by accident as well I guess) It also has a night loading light located on the cover case. Very handy..
Press on regardless!
