~12 months was the estimate given but I am expecting that to move. My circumstances are slightly different to most in that I'll be converting mine in to a camper and have a baby due in a few weeks so likelihood is I wouldn't really be able to use it until next year anyway, so I am in no rush. Not making light of the difficulty a lot of people are in financially but it's also not a bad time to stick the funds set aside for the van in to a savings account while interest rates are on the way up and at least you're getting something back to compensate the delays and help offset any price increases.
I specced it with quite a few camper specific options; swivel seats, reverse camera, tyre pressure monitoring, 80l fuel tank, side airbags, towbar prep, LED lights, power latching sliding door/tailgate, heated washer nozzles. Am buying through a broker associated with forces personnel so got ~11% off list on the van in the end. Not sure where that sits against the discount most people are getting but none of my local dealers got anywhere near it at least.
