IF buying new 15 years ago I probably would not have specked Girard Awning $$$, or AguaHot $$$$, or a residential refrigerator. Now that I have all three they are on my MUST HAVE list (we bought slightly used). Going residential is the best mod I've made, especially after putting too much money into keeping my NoCold 1200 going and YES we boondock often.
I would add tag axle to the list for the increased CCC and the great handling and side radiator of easier access to the engine and easier to keep it clean.
