Did the manufacturer install cheaper hybrid RV batteries, or true deep cycle batteries? What about the method of separating the automotive battery system from the RV battery system if you’re considering a motorhome? Is there a “smart solenoid” or an isolator installed in between the two systems? Or just a simple, electro-mechanical solenoid relay common to the lesser coaches? What about a battery disconnect system? True, many of these better products can be purchased in the aftermarket, but when they come already installed from the factory, that’s a good thing!
* Fresh Water Container - Is the tank well secured to the floor? Is it insulated to keep it from freezing while RVing in the winter? Does it have a properly sized fill vent? Did the manufacturer install a branch tee and include a valve for administering RV anti-freeze for winterization? Some RVs even come equipped with a small tank just for the anti-freeze!
* Propane Container(s) - Is it (are they), properly secured in a dedicated compartment, to the main frame rail or A-frame? Is the main service valve protected from road debris? Is there adequate road clearance below the ASME tank, if so equipped? Is the fill assembly easily accessed?
* Pressure Regulator - Is it protected from the elements? It may be sheltered by a plastic cover of some type. Is it mounted with the vent portion within 45-degrees of vertical? That’s a code requirement and it’s not uncommon to find an ASME tank and attached regulator with the vent portion positioned incorrectly! Also, be sure it is a two-stage regulator! Hopefully US made!
