For me euro mobile. When I was looking for plastic it seemed to have a better rep for quality.I also liked the look of frankia and another I can't quite remember. In the end I chose a better option to build one myself and im so glad I did!!
Went to last year's Motor home show.
Best build quality there and it was so far ahead of the rest was EuroMobile.
Sad bit for me was that they now only build them on a Fiat chassis.
I don't know the models you ask about.
