    I've just discovered I don't understand newtons. The struts on our drop down bed are 2400n, when we've looked for replacements it says 1700n for a Hymer. We bought the van second hand so don't know if 2400n are the originals or have been changed before. The bed has been difficult to lift since we first got it so we are wondering if it has the wrong struts on. Does a greater pressure make it easier to lift or more difficult? Has anyone any idea what struts should be on a Hymer B524 please?

    I would think it would be even harder with weaker struts - assuming they work in tension. A Newton is just a measure of force. The more Newtons, the greater the force. There are approximately ten Newtons to a kilogram on Planet Earth.

    Greater pressure will make it easier to lift.. but too high and it will make it harder to pull down and it may not stay down.. so getting it correct is important,,

    will have a look at mine.. and report back.. AFAIK ..it's the same bed..

    sorry, I can't see the rating only the number

    but I would go with the ones advised by SGS, which are Direct Hymer OEM replacements..

    this is mine.. does it look the same .. IMG_0087.jpg

    Thanks for going to the trouble Scotjimland. No they don't look the same. Ours have retainer star washers and the only way we can access them is from the windscreen end of the bed. Don't know if you can make sense of this.

    No trouble whatsoever.. curtain needed a wash and it's great day for doing it..

    yes.. it does look a different form mine.. and I thought they were all the same.. learning every day..

    I would talk to SGS and ask their advice.. they have supplied many so should know what is correct for your year of Hymer

    a better picture ..

    From Jim's photo the strut works in compression, which is the opposite to what I guessed. Therefore the weaker 1700n strut should make the bed easier to pull down. But the OP's mechanism may be different. To check just look and see if the strut is shorter when the bed is pulled down.

    As you've probably guessed we are fairly new to all this. Scotjimland can you tell me how to get the curtain off. Ours looks well stuck on and has press stud thingys down the side.

    the curtain has a plastic strip that pushes into the strip on the wall... it just pulls off.

    but yours may be different ..

    We've had the struts replaced - this week - on our B640 after looking at the price of Hymer replacements, I opted for SGS - excellent service from them - the old struts were the originals put on in 1997 - the date was on them - the difference in the amount of effort needed to lift the bed is much, much better than I expected
