Hey markus and welcome aboard. I have a Winnebago Vectra that my converter went bad checked out prices on Amazon and order Progressive 45 amp from them with fuses ability to charge battery and pendant monitor in bay to see status of charging. I would think if you stayed within your amperage and find one to fit your location dimensions you would be fine. Good luck.
