I have a 29.5 BHDS. Since I use an Andersen hitch, I have to raise the front of the trailer a little higher than most people. Since I will probably be getting close to the maximum height, it would be nice to know where the fuse is, so I can replace it easily if I happen to blow it.
It's been many years ago since I had electric landing gear. It would make a racheting noise when you hit the limit of the main legs. You're not going to harm anything.
