Why such stigma about owning a park home?

We have been paying a mortgage for many years and now are in a position to escape and buy a park home outright. We have seen some interiors on the internet and they look beautiful. the parks seem to be situated in some lovely country areas, and they seem to have a lot of ground around them. They are large, some of them, and look like normal bungalows. HOWEVER, When i told my family of our intentions at the weekend they were shocked. They seemed to think we would be like those 'big fat gypsy wedding' travellers, (not that I have anything against them) or trailer park weirdos or something. They sensed our disagreement and then tried to be positive, but their negativity was obvious. Why? I have made nothing from being a property 'owner' t was never our plan to do so, but we just make the bank richer and richer every month. We just want somewhere nice to live with a nice view. I can't afford to do this on my mortgage. I live near London. Does anybody have any experience with such a move?? We are in our thirties. Thank you
