I'll add more soon.

I'll also add a picture of my problem: the electric converter that's missing :(

I would see if you could contact the manufacturer (if they're still in business) or model your power demands off of similar vehicles. It's really the sum of the draw of all your 12V stuff: lights (if not converted to LED) can be a significant draw, water pump, furnace fan, etc. 

The breakers are for your 110V supply. The fuses are for the 12V supply. The converter takes the 110V and converts it to 12V so it would feed those 12V fuses. The converter should be really easy to hook up. They usually plug in to 110V via a regular receptacle somewhere near where they're installed. It has 2 wires for the 12V output and a ground on the case. 3 wires and a regular household plug, basically.

The converter will also charge your house battery (and potentially the truck battery depending on the configuration) so you're going to want to get one of those hooked up.

Thank you, Jim!

I went to see a RV specialist and he told me that he had to find the original electric converter (it was two weeks ago and he did not call me back, yet).

But how can I calculate the amperage?  I already have a set of breakers (that look similar than the one houses have, but in a smaller size).  On the front of it, it saids 30 amps.  My guess, at first, was to look for a modern 45 amps converter, but with all the wires in place, I don't know if it can work.

I'll take a photo of that mess of wires soon...

With the 110V breaker box, I have another set of fuses that I think is for the 12v.  Also, I have wires (big wires I should add) that were originally connected to a set of batteries who are located in the big box in front of the cabin (in place of the front bumper on the picture).   Finally, I have two wires that are used for a solar panel situated between the to air vents.

For me, it's very hard to understand what goes where on a converter.  I'd like to do it myself (to save money and, especially, to learn on how it works), but the electricity on this RV is a maze for me.

You don't want the converter that was installed at its birth - they were battery boilers. Try to calculate your amperage needs and get a modern one. My '84 Allegro came with a 45 amp converter. I got a PowerMax 55-amp converter for it and it's been great. It installed where the old one was easily.
