Greetings all. My first post/question. I have a 2017 3.0 V6 diesel Touareg and have just purchased a new caravan. The towing and ball weights of the van are well within the Touareg's stated capability but the rear of the vehicle is a little lower than I'd like with the van connected and WDHs fitted. I think I'd need to source some heavy duty coil springs to fit to the rear of the vehicle but am experiencing difficulty in sourcing same. I'd truly appreciate any information that could be provide to assist.
