Hi I had a small area of delamination in my caravan which I have repaired, it has pretty much cured the problem but there is still a slight bounce to the floor, nothing serious and I'd say at least a 90% improvement on before the repair, I have had an idea which I would like peoples opinions on as to if there is any reason not to do, where the slight bounce is in the floor is directly above a cross member of the chassis, is there a reason for me not to insert some sort of block between the chassis and the floor? I put a jack under the caravan in more or less the same place that the block would be and it got rid of the movement totally, the cross member is what you would think was an axle except the van doesn't actually have an axle as such as the wheels are really attached to an arm off the chassis, any safety thoughts or other technical reason why I shouldn't go ahead.
