Dubman bewteen Alan and Ray we have a wealth of info just in these two guys if you are going to undertake the change do keep us up to date with the change..

Barn doors in my opinion are the way forward my nest one if i can will have them, a simple shelter like the Bays had easily made is all you need, can't find an image right now but it goes over the toip of both doors sheltering you on then all sides i want something like this probably for mine though. If i stick with a tailagte obviously...

A sort of variation on the one VW did themselfs that stored in the rear door..

Seems the best way,then if i cock-up won't damage any new paint

Wish you luck Dave rather you than me, i would personally leave it to the professionals or bought one with a tailgate as i have coz im a coward i sometime however wonder if i might of been better with barndoors however, and am still in 2 minds with regards to my new build as to which route to take, as my next will be a lwb high top hopefully if so the doors could be a bonus as it is my intention to have a toilet tent built to fit into the space the barn doors leave although ones are available for a tailgeted version also so not quite sure yet ahhhh all these desisions and it still will always almost without fail be an unfinished project
