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 websiteThe 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.
