I thought I read it somewhere on this forum about adding seats to the cargo transit but I can't seem to find it. What I'm planning is to add an oem 3 person seat with the oem mounting rails to my 148" wb cargo van. The seat is going to go right behind the driver/front passenger seats. Is this going to be an issue or not too big of a deal? Like I said, I read somewhere of issues in doing this but can't find it. I don't have the seat in my possession yet but I'm supposed to get it this week. Thanks
