Mini-split interference?

I currently have a perfectly fine set-up with the R10 in a huge metal outbuilding and it performs fine, but when it starts to warm up again (NE Iowa) I'm going to build an enclosed 12x20' finished room inside of the outbuilding to house the simulator so that I can comfortably use it in the summer and winter.

I've seen mixed messages online about using a mini-split AC/heating unit with regards to interference. Does anyone SUCCESSFULLY use a mini-split around their R10, and if so, any helpful tips as to placement?
