Maxxair remote control vent fan question....

I recently installed a Maxxair 4500k series vent fan in the bath of our new 5th wheel. The wife would now like one in the kitchen, would two remote control fans cause issues? I would almost bet the remotes have many different channels and would not interfere with each other. Anybody running two or more of these fans? I have e-mail the manufacturer to see what they say.
