Hello MrVcross, and welcome! Underneath the tongue area, there are inline fuses encased in green plastic covers. Follow the tongue mounted battery box wires underneath the tongue, and you'll see the relatively fat wires- with inline fuses on them, one fuse for each slide. There aren't any fuses for the slide outs in the converter power panel box. They are 30 amp automotive style bayonet fuses. I'll bet that is your problem!! P.S. There are many other hidden fuses on your camper, as well. Most built in appliances have them; AC, Fridge, heater, just to name a few.
Good luck, hope that fixes your unit. Randy
