Ok, so I tried to fit a roof box to our Autosleeper Pollensa, but not having much luck The MH came fitted with a roof rack and ladder, although the bars which run across the roof are too far apart toward the front and too close together towards the rear oh: So basically I need some kind of cross bars to fit to the already fitted roof rack bars which run the length of the MH. I've seen the fiamma ones but they appear to only work with fiamma. I cannot seem to find any universal type bars. Does anyone have any suggestions??
