Does anyone know about how much power a 38ft 5th wheel with 2 AC's (which run all the time here in south texas during summer) should be using. I have the highest electric bill in the entire park. By more than 100 dollars. Was running around 160ish 2 months ago. Its in the 260 range now. My neighbors run both ac's as well. There bill is just 140 to 160.. Please help. I think i may have a faulty meter?

Something is wrong. We cool a 3000 sq ft home for that much. Many possibilities but 'something' is not right.

RVs are much less insulated than your stick home. Walls a couple of inches thick. There is no 10 inches of insulation in the roof. Slides often don't fit tight. Windows are not nearly as insulated and efficient as the standard double or triple pane home windows. It isn't sitting on the ground, so it gets no cooling or insulating effect that a basement, crawl space or slab provides. Your home is likely surrounded by grass, shrubs and other landscaping that does not reflect heat like a gravel or concrete RV pad. Your home AC is likely much more efficient than an RV. Finally, I doubt you enter and exit your home nearly as much as the average RVer does and when you enter and exit it is often into a secondary room (garage, mud room, entryway etc) the isolates the heat gain from the outside and the cooling loss from the inside. Square footage is a small piece of the puzzle.

Still not buying that this is normal. Insulation or not, it's <400 sq. ft. and area is a LARGE piece of the puzzle. More of an issue is the total volume to cool. Our minimum ceiling height is 8ft,and most spaces are 9ft or more. My home has 32 large windows and six exterior doors (we have a courtyard). We have a refrigerator and freezer pumping heat into the space. No comparison in total heat load. He has a problem.
