Before we jump too high, some "make-sure" questions, perhaps?
I see an option for inverter or not inverter, so do you have an inverter. If this is Greek to you, do you have a gizmo that lets you use battery to make AC to power things like microwave when you are not plugged in or running a generator?
Also when you speak of "front seats" are we speaking the driver and passenger seats, not the dinette, etc. ?
Makes it much easier to get down to the right answers for where to look if we get those details straight!
This is a link to the drawing and might get you some ideas:

If not used to reading them, look at the load center and find the breakers on the drawing. Looking at the left of the load center, there is a 30 amp, then two 15 amp. Since you don't mention trouble with the first set of rcpt (receptacle), I went to the second and see it feeds down to a funny sqwiggle like a lazy "S" which is where the option of inverter or no connects. Sqwiggle 40A is for no inverter and 401 is with inverter so follow the right path. If you want to know what the triangles with numbers mean, look down to the left on the drawing for explanation.
Give it a go and see what comes up and if more questions come back and we can do some more thinking.
Think of it as a road map and somewhere there is a hole in the road! Not hard to fix---once you find where the hole might be and the first step is finding which road to follow!!
Good luck with the chase.
