I'm going to guess you will have the same issues putting 44s on your van that anyone would. The engine on your van sits right above the axle in the same place my Blazer does. I think your wheel openings are probably smaller though. So without fender trimming you would actually have to go higher with the lift than I would. Unless you did some trimming. There are a few sites with 4x van information but not many.
