That combination will suck but it won't amount to a death trap, if that's what you're asking. You've got enough caveats in there I think you know it's gonna suck. You didn't elaborate any on your family size and what alternate vehicles might work but I'm going to assume young family with kids. Although to be fair that description could probably fit a lot of the older rv.net set too, even if the dog is a 8 lb runt. You could give it a shot and if it doesn't work out just plan on trading the van in for something more suitable.
