Not familiar with your model, but you should have a converter/inverter in your rig. Usually low down,approx 12"x8" cover plate. If you pop the cover, there will be a set of LED lights - if one of them is lit, it signifies a blown fuse.
However, fuses blow for a reason !!! I would suspect that you may have a chaffed wire on the slide out which is grounding out and popping the fuse.
