It still wasn’t clear then if even that motorhome classification would change the speed limits.
And the VED would nearly double.
VED stays the same thankfully, otherwise us big van owners would be be paying top band luxury 4×4 rates!
Me neither, but I believe it’s to do with the fact you don’t have a van fully loaded with a ton of stuff on a pallet in the back, it’s the only thing I’ve heard that makes sense of it.
A lot of conversions (especially home build ones where the interior is not paper thin caravan style furniture) are heavy, one of the main concerns secondhand is whether they are overweight. Especially the big race van conversions.
