Travel trailers & generators?

Im going to purchase a 24 or 25 ft travel trailer in the near future and would like to attach a gasoline generator to it for powering the lights, microwave and air condition unit. (Most of the RV's in this class to not come equipped with one.) What would be the best way to accomplish this task? Thank you.Travel trailers %26amp; generators?
You should also attach an rv backup camera system. It could be hard to drive such a large vehicle and our rv back up camera has already helped thousands of autos reverse safely.

Most travel trailers are 30AMP 120VAC service. This equates to approximately 3600 watts of power. Of course, that's a rough estimate since it depends on the type of load, etc. First thing to do is make sure you get a generator with enough capacity. Some generators, for example, are rated at 4000 watts, but only have 20AMP 120VAC circuits. Won't do any good. Make sure you have 30AMP capacity on 120V. There are many ways of mounting a generator to the trailer... rear bumper racks (be careful of weight) and tongue-mounted systems are both very popular. I'd suggest just sitting the generator on the ground rather than mounting it. Two reasons: First, the generator will be more easily accessible at home should the power fail. Second, with the generator on the ground, you won't feel the vibration of it running when you are trying to relax inside your camper.
