Side to Side Weight Balancing of a Caravan

Hi all

Calling all people knowledgeable in caravan design.

I assume when a caravan is designed the aim is to balance the weights of all the fixed items both fore and aft of the wheels but also from side to side such that the caravan is not heavy on one side.

In adding some equipment to the van I keep coming back to the most ideal location would be on one front side of the van but this will add around 90Kg to one side. I could centre it at the back of the van but experimenting with that reduces ball weight to about 80Kg.

My concern is whether this is too much side to side imbalance and what the consequences might be in towing like that ?? Maybe that is better than towing with a lighter ball weight ??
