So I've done a quick bit of reading up and I cant see why you couldn't just stick one of these ( anywhere ) in the van.. then if it gets pinched or you just can trembler where you parked it , you just get your phone out and see where it is! approx cost £25.00 and batt lasts a year. https://www.apple.com/uk/airtag/?af...2984327644_&cid=aos-uk-kwgo---slid---product-
