F45 or the F35 Pro, looking at 3mtrs.
It will be fitted to a westy pop top.
My thoughts are: F45 may be bulky looking at the size of the mechanism, but is the F35 (@ 3mtrs) too lightweight for our weather?
Decided to invest in a Fiamma as last week whilst on holiday, i found my 'Just Kampers' sun canopy in the next field after a storm. I must admit i had been drinking, but i'm pretty sure i attached it to the van when i put it up

The Idea with the Fiamma is that i can retract it before it rips off and chases the local live stock in the next field!
