vertical ripples in bodywork (1 Viewer)

[nannyjan]

Just wondering if anyone knows what is causing several vertical ripples in the bodywork of my motorhome. My motorhome is two years old at the end of May and I will be having the habitation check done to keep the 5 year water ingress waranty valid. Do you think that water ingress could be causing these ripples. Any advice appreciated.

A photo of your ripples may be useful....

I would get in touch with the supplier NOW, could be delamination, unless you are in the habit of driving it into a brick wall.

Inside outside?

Our Elddis had ripples too!

I think it is because the aluminium skin has a high expansion coefficient. When it gets warm, it wants to expand but has nowhere to go!

I might be wrong on this, but it seems feasible!

As for water ingress causing it, I would say it wouldn't be a factor unless the ripples are in the shape of the wooden frame beneath!

Hi Callum, the ripples wouldnt show on a photo as you can only see them when standing at a certain angle and catching it in the right light. But thanks for your advice. I am going to take it back to the dealer asap as the more I look at it the more I think it is cause for concern. Many thanks Jan

Is it rippling where it sticks to the side batons IE in-between the batons ?I do know some makes do not stick the roof and let it flap but this does not happen to the sides.Take it back a see what they say ? (if not happy with explanation)also get a second opinion on it from a caravan/mh repair shop THEY SHOULD GIVE FREE QUOTE /ADVICE

if its only visible at certain angles and light conditions i would say theres nowt wrong.

it will be where the outer skin is glued to the side wall frame which will never be totally flat over such a large area

Gently push where the ripples are...

If there is give, or slight movement definately "Delamination...

from certain angles you can see the shape of the timber frame on mine too

just put it down to contraction of the ali skin maybe i'll look more into this now.
