I can understand why LDV is staying a bit quiet on this one. The fact is, you’ve modified the vehicle from standard, and LDV has absolutely no idea of the exact changes you’ve made. That makes it very difficult for LDV to comment. You’re probably going to get a more informed opinion by talking to the company that carried out the camper conversion. They may have seen this happen before and have a solution ready made.

As for the actual problem, even though you’re still within the Gross Vehicle Mass (GVM) limits, you might find that the weight of your conversion is not evenly spread across the front and rear axles. Placing heavy stuff at the rear of the van will inevitably compress the rear springs. It’s just a question of how much. Don’t forget to weigh the vehicle with all your camping and gear on board and the fuel and water tanks full, too, as this is how you’ll be travelling. Which means loaded up like that represents your real GVM.

Possible solutions include a firmer set of rear springs that will cope with the load better, or even a set of helper springs (possibly air bags) to assist the standard springs. Either way, these modifications need to be carried out by a specialist and may even need engineering approval to remain legal on the road.
