The manual says the Orion 12/12-30 should be mounted vertical with wire connections at the bottom. My location really needs it upside down, with the wire connections at the top, to fit in my space best. Can the Orion be mounted upside down?

That will be fine for cooling as long as the fins are still vertical.
However, IP43 protection will no longer be effective:
This means that water falling as a spray or objects more than 1mm in size could affect the unit if it is mounted upside down, If you can mitigate against these hazards then you'll probably be fine.
This is in the basement area of my 5th wheel. If I have water spray, I will likely be replacing more than my Orion...
I think IP43 will be the least of your worries. It is near the MultiPlus which is IP22 when upright, so you'll be fine I think. It will still get the cooling that it needs.
