Its the same thing except theres a reversing valve that switchs the freon around.
Plus the 50 amps is plenty for 2 even 3 hps.
Look at the motorhomes. They have three and only have 50 amps.
Remember you basicly have 100 amps of power. Each leg is 50 amps each. Unlike a smaller camper only has one leg of 30 amps.

Yes and no. It is just a changing of valves, but there is also a defrost cycle that is used and a heat strip. Those two functions cause it to use additional amperage.
As for units with multiple heat pumps, the ones I’ve come across use a power management system to control how many are being used, typically only two at a time, but will shut one down if needed when running additional accessories such as microwave, coffee pot, hair dryer. Montana’s don’t have a power management system to monitor and control the power. I’m am strictly guessing at the reason based on my understanding of the systems. It could simply be a cost issue, but I don’t know if any 5th whee that has multiple heat pumps
