Definitely a Crows conversion. You can always tell by the steps and bumpers.
The interior actually threw me off a little bit because when I owned it, the counters and stuff were woodgrain, not white. The white is actually an "upgraded" look in my opinion. The teal fabric screams early 90's, but it could have been worse with the coral/salmon color SMB used.
To the OP who is interested in this van, I remember it being grossly under powered. I'm sure they changed the gear ratio to accommodate the bigger tires, but give it a good test drive up hills or grades to make sure it will do ok.
