Did you have an existing trailer harness, or did the rental place hook one up?
The turns, hazard, and brake are all the same lamp at the rear. Sounds as if a something in the circuit has been shorted.
Suggest to look closely at what the trailer rental place did - the problems didn't start until after they did this work. To be blowing fuses of that size, it's a pretty good short. Perhaps something in the trailer connector itself is bad or crossed over.
