Has anyone ever used one of those 20" x 60" haulers that slides into a 2" hitch receiver on the back of your pickup?

Did or do you like it?

What I am wanting to do is put a hitch on the back of the RV trailer. And put my 5500 watt generator on it. Mostly for the times that I am maybe parked at night traveling at some Wal-Mart parking lot. Or maybe at some fireworks tent location before the power is hooked up. Granted the RV runs off of a good 12 volt battery but it would be nice to run the microwave to heat up some water for a cup of coffee. OK I ADMIT IT I AM A MALE AND I DON'T LIKE USING ANYTHING BUT THE MICROWAVE. BECAUSE IF I USE THE STOVE I HAVE TO DO DISHES!

My neighbor gave me a receiver hitch for the RV so all I have to do is have it welded on the RV and purchase a carrier.

Any ideas?

Thanks!
