Trailer towing is being discussed on e-46 board currently. Assuming you are being reasonable about trailer size/ weight, you need to take the same common sense precautions that apply to taking any 9 yr old/ 150k vehicle on a road trip. Inspect tires(don`t forget the spare!) brakes, belt(s) hoses etc, change oil and most important, Is your cooling system marginal in any way?
The additional "work" imposed by towing could cause failure/overheating. Remember, that if you`re towing a box trailer, not only are you adding lbs but also considerable aero drag.
If it`s not a rental trailer (i.e. yours) be sure to inspect/repack those oft neglected wheel bearings, many trailers have small diameter wheels which spin a gazillion RPM on the highway.
