Popped over to Wales yesterday and saw Malcolm from Whitbread about a custom roll cage for my Defender Dormobile.
Not an easy one as 3/4 of the roof opens up, as per photo. We came up with a good solution and compromise which is to just protect the driver and passengers in two rows of seats. If I roll then the Dormobile roof is finished anyway.
Its going to have tons of bracing both down the rear and on the pillars between the front and rear passenger doors.
I've seen lots of photo of other cages that don't seem to be anchored to the chassis, these ones have plates which are welded or bolted to the chassis so its this that takes the load.
Also the sections are all welded together, some of the others look like they are bolted together. Someone said they use lighter weight steel, from what I saw it was very thick and solid tubing and the welding looks the best I have seen.
Will post a photo when its completed, probably in a months time, it will be an odd one i can guarantee. I have to leave the Defender with them for a week to fit as its not standard which they say they can do in four hours.
Price wise its not cheap but its not expensive either, cheaper than other quotes, and they only need the vehicle for a week, not six weeks as another company quoted.
PS I don't work for them just saying it as I see it.
