Looking through past topics I came accross the excellent top produced by Piddy.
It appears there have been problems aquiring the caravan chanel to use accross the screen.
Piddy: If you let me know which dealer you got your chanel from in Norwich and what type it was (I believe P or F section), as well as the length required for a vehicle. If it helps I am more than happy to try and secure a quantity of it for those who want it, as I live on the edge of Norwich.
