You never know your van might turn up somewhere.
A mate had his stolen off a drive a couple of years ago, van was later found abandoned on the side of a road.
A couple of bits were missing but most of his setup was still intact.
If I was you I'd start a campaign, knock doors in the area, put up a few posters offering a reward etc. It might just scare the scumbags into ditching the van somewhere.
The best case scenerio you could hope for is to at least get the van back with half your kit still there.
