Welcome to RVF,
@Rogersde63; glad to have you join us. And, sorry to hear you are experiencing issues with your 5th wheel. Without knowing the specific make and model of your 5th wheel, it is a bit hard to remotely diagnose the problem.
In general, electric slides are moved with an electric motor and star-wheel or chain drive. Some of the failure problems include loose motor mounting bolts, misaligned slides, a failed motor and/or clutching mechanism, lack of lubrication, etc.
I think the first order of business would be to do a search and determine where your slide motors are located and how many there are. Check all the mounting bolts and be sure they are secure.
If you have multiple motors and one fails, the remaining motor(s) will not have enough power to more the slide and will overload, resulting in a blown the fuse. Or, they may move one side of the slide, but not the other, creating a misalignment and binding. Again, this will result in a blown fuse.
Asfor the panel pulling loose, I would contact the dealer you bought the trailer from and see if that would be covered by an extended structural warranty. If not, you'll need to find a way to re-glue the panel, using some crews to secure it, at least while the glue dries.
For the stove burner, the vibration of going down the road will vibrate things loose. You will need to replace the screws and check them periodically to ensure that they are tight.
Good luck.
TJ
