Moisheh, not missing a thing. If you have a DP you already have the requisite 24/7 AC power and $are not an issue. Lots of folks with fivers, large tt's and class A gassers consider residential units. If they did not hear the whole truth they might make a very expensive change and end up exchanging one set of problemns for another not to mention wasting a lot of money. Any time you incease your dependence on AC you diminish your options and freedom that led most of us to RV' ing in the first place.
Any DIY residential install is not going to be well received by the manufacturer, read the owners manual particularly the section entitled "Installation requirements" as they generally do not allow RV installs if you want your warranty.
We are on the road, greetings fom Brinkley, Arkansas so if you want to argue, I mean "discuss" this further you will have to do it without me. Time for a cocktail filled with crystal clear cubes from my AC/LP frig. Cheers! :B
