Any grounding situation can be hazardous or destructive under the right circumstances. Best rules of advice, follow the given specs in the system that you are working in.
As for technically, in most states trailer frames are required to be bonded to the power ground by an electrician upon initial set up. By using a trailer or ibeam clamp, scrape loose rust away from your surface area and tightem down the clamp. The clamp usually has a pointed attachment bolt wich penetrates into the stell beam. This does not ground your system, it bonds your system to the electrical service ground.
By using just an 8' ground rod, without bonding to power, you are actually increasing the chance of an issue. "Differentials of grounds" In short, the power ground set up may have lease/more resistance than the ground rod that you just installed, and a negative charge follows the path of least resistance. This can cause erratic pictures and possible injuries to people touching tv's and vcr's.
For cable tv installations, if you have a ped within 30' of your demarc, and no viable electrical grounding source, the install may be left without an additional bonding attachment, only if the tap in the ped is ground to a #6 gw and 8' gr. Even though you still have a potential for differential, go figure. It's in the NEC Code Book.
