The purists will say to upgrade the whole van. I would ask: what do you plan to tow, and how much, how often?
If you are going to grab a U-Haul for a day to haul some lumber or a load of mulch, go for it. If you are wanting to tow a small camper (likely a pop-up), should not be a problem. I think your tow limit is 1500, but might be as low as 1000.
Since the "tow package" is mainly an engine oil cooler, just be sensible about it and don't overwork the engine to get it hot and keep it hot. Shorter trips around town, as mentioned above, will be fine.
