I know there's a similar thread in 'Expeditions' but I'd like to discuss something a bit different ...

What do people think of fitting a large roofrack to the Disco, sheet of ply as a solid base and using a 'normal' tent (that'd fit the roofrack, obviously) pitched on that? Don't want it for expeditions, just for a weekend or a week, maybe two, away laning in UK, possibly France.

Has anyone done this?
Anyone see any problems with it?

I think practically, providing the floor area of the tent fits, then pitching should be easy, 'specially with something like my little pop-up tent, and the roofrack sides could be used to hitch the guylines to.

one problem trees and walls when laning as you know well you would not get down some lanes

Not worried about that so much, more about the practicalities of camping on the roof!
