Frequently Asked Questions:

Is 4000 watts big enough for our R.V.?  Yes over 90 percent of our sales are 4000 watts 30 amps.  Because most R.V.s have a 30 amp cord and 30 amp main panel this is the ideal size for most all R.V.s today.

What will a 4000 watt 30 amp Gen-Box run?  This model is designed to run a 13,500 or 15,000 BTU air-conditioner plus the microwave, plus the T.V. / VCR and some lighting.  When your not running the Microwave you can substitute other appliances such as: (coffee pot or curling Iron)

What if our R.V. is 50 amp?  No problem as long as you are only running one air-conditioner at a time you still only need the 4000 watt 30 amp.  Simply plug in a 50 to 30 amp adapter and plug it in.

Isn't bigger better in the case of Generators?  Actually for most R.V. ers bigger is not better.  5.5-7.5 larger units consume so much fuel that you cant even run the air-conditioner over night without refueling on 12 gallons.

How long will the 4000 watt Gen-Box run?  With the standard 12 gallon tank you will enjoy 35-50 hour runtime depending on the load.

Can we put the Gen-Box on the back of our R.V.?  Yes infact we offer a platform that bolts to the bottom of the Gen-Box and slides into a standard 2 inch receiver hitch.  Simply have a hitch that will support at least 500 pounds installed on the rear of your R.V.

How do we get one installed in our truck?  We ship Gen-Box's all over the country every day.  You can stop by any of our nation wide shipping points and they will set it in the back of you truck!  Coming to Arizona? we will install your Gen-Box for free if you come to our factory.
