Hi Great install. I've installed several and would say that it is important to finish your exhaust out the side of your van. Otherwise carbon monoxide could bleed up through into the van and kill you in your sleep. I would even go as far as to make sure the tail pipe sticks out at least 50mm clear, and not under an opening window. Best regards.

Also you definitely don’t need that charger despite a few videos that wrongly advise that one ( not bad for the firm that makes and sells them  eh? ) most chargers now are compliant for smart alternators for want of the correct name which I forget ,

Nice installation, very clean. Could you tel us how many time you spend to this installation ?
