Trailer brake circuit breaker advice. (self.cars)

We're preparing to move about 1000mi.

I'm getting my truck ready to tow a trailer for our three potbelly pigs, two cats and a dog.

'98 Ranger XLT with 4.0L V6, auto trans. Rated for 5900lbs tow, 9500 gross. Even has the overdrive disable and good rear end ratio.

I'm adding a Redarc Liberty brake control. The 7-way plug kit I got includes 30 and 40 amp auto reset breakers for the control and trailer power.

Here's the thing. I don't like the idea of an automatically resetting breaker at 30 amps or more due to the risk of fire or frying the electronics in my truck. I would prefer to install manual reset breakers. I understand that an auto reset might allow some brake capability in the event of a short and that is why they are used. I just don't feel like the auto breaker justification is that likely vs the other risks of auto breakers.

How long does it take the auto breakers to reset?

What are the real world risks using manual reset breakers?

Opinions/thoughts greatly appreciated!

That's a pretty good idea. I've got Maxi fuses in 40 and 50amp values. Maxis are slow blow, IIRC. May do this.
