Responsible Use in the Newmar Canyon Star manual?

It is mostly a CYA thing the manufacturers put into their manuals to get out of paying warranty claims that get too expensive. There are also regulations and rules about permanent dwellings that would be expensive to comply with. Full time or commercial use is very taxing on RV systems and as a result full timers would be more likely to file more claims and for larger amounts. A good example is one of the largest RV manufacturers in the world installs "modified sine wave" inverters into their rigs with a residential refrigerator and microwave convection oven. They know that the refrigerator will fail after about 1 - 1.5 years if running all the time due to the poor power quality. They made the intentional choice to use this square wave inverter knowing that most people will use the RV for only a few weeks in a year the microwave and or refrigerator will last at least past the warranty and it won't be their problem. Engineering a coach for full time use is a very expensive prospect because everything needs to be made more sturdy and able to resist wear. There are a few manufacturers that do build coaches intended for commercial or full time use and they are very expensive and at the same time have more industrial components. They are also much heavier for a given size of RV. You will see these most commonly in the racing circuit. These coaches are 80,000# with the trailer.

If you look by your front door, or some other place on your RV, you will find the RVIA label for your RV. Here is their website: RVIA website
The second paragraph says:
An RV is a vehicle designed as temporary living quarters for recreational, camping, travel or season use. RVs may be motorized (motorhomes) or towable (travel trailers, folding camping trailers and truck campers). Off-road vehicles are not included in the RV definition.

The difference is that to be classified as a permanent housing residence, it must be built to the standards set by HUD for either a manufactured or modular home which is much tougher than for a temporary structure like an RV.
A manufactured home (formerly known as a mobile home) is built to the Manufactured Home Construction and Safety Standards (HUD Code) and displays a red certification label on the exterior of each transportable section. Manufactured homes are built in the controlled environment of a manufacturing plant and are transported in one or more sections on a permanent chassis.

I was reading the Newmar Owners Manual yesterday and came upon this;

Responsible Use. Your vehicle is designed to be used for recreational or temporary living purposes. It is not designed to be used as a full-time residence or for commercial use.

My wife and I have not plans to use the Canyon Star as a "full-time residence" but we do plan to spend a few months or so each summer in it.

Why does it say its not designed for full timers, I don't get it?

there simply not designed nor constructed for 24/7 365 usage.therefore they limit their liability by declaring such
u need to get into a mid to upper level diesel pusher for full time usage. I seriously doubt any manufacturer installs a inferior inverter knowing the fridge will fail after 1.5 years
I have a 8 year old MH and no RF and yet it has a RS3000 True sine wave(best one)

So it's not a diesel / gasser thing? I know the diesel is built on a stronger chassis etc. But if I'm reading you right the "non-full-time" disclaimer would apply to the lower and mid priced diesels as well right?

I think its really whatever the manufacturer wants to portray?
that is what they feel each model is capable of
I know my 2008 40 ft allegro bus is built a hell of a lot better/superior in every way compared to my friends 2007 Georgetown XL gasser

For the difference in money it should be, but does your owners manual have the same kind of disclaimer?

Even a multi-million dollar Prevost coach is not designed for full time living, according to the RVIA certification and they DO NOT meet the HUD requirements to be considered a full time residence. You can spend millions but a Prevost is still an RV and certified by RVIA as a temporary residence.

yes that's my point and such the makers will put a disclaimer in units they feel wont stand up to full timing
The RVIA stipulations and hud and all that chit really has no bearing on what your manual has stated
NO my manual has no such disclaimer

But in reality(my take/opinion) using a broad paint brush the term RV encompasses thousands of makes and models and therefore seeing in general terms a Rv was intended for holidays and weekend campouts and
has so many different construction ideas and codes that many times are far different than a S+B house they simply say what they say
because of the general accepted usage

x2. This is the one and only reason. RVIA certification. Not designed or built to the standards for a full time residence. It has nothing to do with gas vs. diesel. Cheap vs. expensive.

Except for the fact that it matches what the certification label means on each and every RV, regardless of price and regardless of what your manual says or doesn't say. The label itself means it is designed and meets standards for ONLY temporary housing. You CANNOT build an RV, and sell it to the public, without the certification label.
