    Roof rigidity, roof racks and tropical roofs

    Hi all,
    Is there much flex in the roof of 110 wagons? If a full length roof rack was fitted that was very rigid, would it cause any problems, such as cracking the joins at the pillars, popping out the giraffe-viewing windows or similar?

    I want to make a tropical roof, and being an 80s era 110 have the ribs on the outside of the roof. If I was to bolt/rivnut a sheet of aluminium straight to the ribs could it cause the roof to stiffen and hence be a problem? Would it flog the mounting holes out and pop the tropical roof off?

    My idea is to get some reasonably thick aluminium, either plain or chequerplate, so that I can walk on the roof without deflecting the roof skin. I don't want an actual roof rack as they can be bloody expensive and heavy. It will also allow me to make a quick and easy mounting method for my RTT.

    Any advice or opinions welcome!

    I've seen what you call a RTT. You are too generous to give it that description. It's a chiropractor's wet dream. :P MLD

    As for your question the body is isolated from most of the chassis flex so I dont think a rigid roof rack or tropical roof would be a problem.

    I didn't think there is any isolation between body and chassis of proper Landies, hence body lifts are nigh on impossible, and also why when flexed it takes a fair bit of effort to open and close the doors...

    The body is bolted directly to the chassis so whatever it does the body will do, having said that the body is pretty loose.

    Just had a thought while reading, what about using some rubber isolation mounts with a stud fixing on both sides. Use some rivnuts in the ribs and acorn nuts on top of the sheet.

    Interesting thread I had always wondered if my full length rack was adding to the lack of flex and it seems to have got worse since fitting the foxwing which would make sense. I wonder if roll cages make it stiffer again.

    The Perentie wagons have a fibreglass tropical roof that is mounted to the three ribs down the roof and it has no flex at all so I think mounting aluminium there wouldn't be too much of an issue. Mounting a RTT to it though without support from the gutters may be an issue though. It's a lot of weight directly on the roof.
