These guys are experienced, yes, but that's never any guarantee of anything.
I got a permit to place it, but there's nothing there about setup or configuration. They got a permit to move it. As far as vapour barrier goes, there's none under it now, and no word about that. I haven't seen it on any other one around here either. What's the purpose? I don't think it's done around here normally. Usually they're just up on blocks, that's it. However, if the vapour barrier is a good idea, I might bring it up with them, after all it's pretty cheap I think.
There's nothing on the outside except a porch light which they are taking off anyway, no A/C or anything like that. They are also taking down the electrical mast for clearance, removed all the skirting (it was all crap anyway), got it up on 4 axles & wheels today, and installed a hitch. Not actually moving it today though, probably going to be Friday after tomorrow's rain stops. Once they get it here, on blocks and levelled, I think they are done. I handle the plumbing & skirting, electrician for the electrical.
