    Personaly I would NEVER screw anything to the roof,with the constant movement its only a matter of time before you get water ingress.If you must have the extra storage go for a backbox,its much easier to get in and out of without always climbing on the roof.

    We bought a van with a roof box allready on, left it for 2 trips then got rid of it and noticed the difference straight away in performance / fuel economy both much better without it. put the box on the back if you have to but deffinately not worth putting on the roof.

    Hi Frosty, ours is stuck and screwed :thumb: never screw anything to your van without sealing it :thumb: The back box would get my vote :thumb: if possible, if only because the roof-box knocked 4 mpg off (used to get 31 mpg now only 27 mpg less 10mph off top speed :cry:)

    Hi Frosty,

    As you are in Worthing why not drop by one weekday and ask Glenn or Ian for some advice, we have roof rails for Fiamma boxes etc.

    No sealant? not a chance. for a few quid for a tube I would deffinately use it. You can use a fitting kit without rails though.

    thanks for replys,i have been reading the thread about fixing solar panals to the roof and some are saying to use sikaflex512 ? do you think sikaflex is strong enough to stick my box brackets,then bolt the box to the brackets?or when im doing 60mph will the box be landing on the bonnet of the car behind me,regards frosty

    I have silkafex 512 holding my dome on. I was really nervous about it but, touch wood it seems ok. However a top box would weigh more and especially when its loaded.

    if you give it a try, let me know so I dont follow you.:Rofl1:

    I have 3 solar panels with the brackets stuck down with Sikaflex and they have been up there for a few years now with no problem.
    I think a topbox would have more turbulance,so would not risk it.

    Hi Frosty, you will need to screw / bolt as well as stick :thumb: Sikaflex does not stay stuck to plastic :Eeek: In deed most leaks occur when plastic meets ali panels or roof lights.To get over this on my self build I used both Sikaflex (to stick ) and GP Mastic to stay sealed. :thumb: By the time the sikaflex gives up (may be a couple of years down the line :Rofl1: ) the GP mastic will still seal the job and quite a bit of force is needed to lift either roof box or sky lights :thumb:
    You can buy ali sheets quite reasonably priced and stick a large sheet over any holes made after taking the roof box off :thumb: stick straight on top of existing roof ,it will also help strengthen it :thumb:
