I have a potential tenant that's asking if I'd be OK with him parking his aero trek aircraft trailer system on our tie-downs. http://www.aerotrek.aero/trailers.htm Has anyone had any experience with this type of operation and what to look out for? My concerns is how will this be secured to the apron and I'll need insurance for both the aircraft and the trailer system. This is essentially a mobile hangar. Is there anything else that I should be concerned with?
