TC Refrigerator blows 30 amp fuse in truck

I have a 2005 Lance truck camper with a 3-way refrigerator. I've tried using the DC setting twice and both times it caused a 30 amp fuse to blow in my truck's fuse box. It seems I read somewhere that a larger wire may need to be run from the truck to the camper. Any ideas about that?

    Each refrigerator has label saying the power draw in each mode.
    12V draw is usually in 15-20 amp range, so unless you have bigger than usual refrigerator, something else has to be wrong.

    My fridge on DC draws between 34 and 36 amps.

    I suggest adding a 2nd charging path direction from the starter battery to the "house" jars and using wire appropriate for 50 amps with a 50 amp automatic circuit breaker.
