Hi Dave
I just found out today from
Hillside Leisure at Derby ( good folks I bought it from ) that the roof fitting/adaptor is no other than the ones fitted by Wellhouse Leisure and is not one from Fiamma.
He showed me how to take the inside lining out to get to the bolts and also told me how to drill out the fitting bolts to allow me to put some
proper support behind the fixings to stop the roof cracking further.
It's only been on a year and I think it's a poor job to fit something like that without some kind of proper support.
The van is in for repairs, the motor on the drivers seat (front and back adjustment) doesnt work and are fitting me a manual seat free of charge

and you can't ask for anything better than that!
Regards
Eddie
