If the setec thing is the things with the the fuses in, then it and our battery are on and in the club lounge nearest the fridge. @Bellbirdweb , I'm sure you'll understand where I'm talking about seeing as though we have the same model van. Jayco put them there after they moved the hws and pump into the front boot
@Smirke Yep that's the setec, and ours is in the same spot. There is an empty space under the seat that looks like its screaming out to be filled with a second battery.
