I notice that on some of the more modern motorhomes with beds over the cab they are lifted by gas strutts. Allowing more head clearance in cab whilst bed is not in use. My van allows the bed to be split in half but it is a bit of a pain (in more ways than one) especially when the bed is made up so I was wondering if anyone with an older type van has been able to add these successfully and if so where would i get strutts from.
