i know people that do this. a PA32 works well as long as the body is being transported in either a transport casket or a body bag. which is how most are transported. the PA-32 does not have the room or the weight capacity to haul a full size casket, most are very heavy without the body in it. it can be a very viable business if you are in an area that has no major airline service close by, the regionals do not transport human remains for the most part, its a main line only cargo. one caution, its not a job for the faint of heart, it can be a bit unsettling, especially at night.
