@Frosty1979. Welcome to T6F. What mistakes did you make? Such things are always good to know about so that others can avoid repeating them wherever possible
The tyres were not all my fault. There was a mix up when they were fitted and they were not the correct load rating for the van, only 100 not 103 as it's a T32. I'm sure they would have been fine but always better to be safe than sorry, so the dealer is sorting that out for me.
In regard to insurance, I just went with the cheapest quote (Admiral) and didn't think about the modifications we were going to make, and how that would impact the price with insurance admin fee's every time I changed something. So I cancelled that and went with A Plan. A bit more expensive but I think I'll save that in fee's over the next 12 months and the level of cover seemed better suited to us for camping.
