Can't help with the towing. But we had 4 white Chevy Express 3500 15 passenger vans for our business, one 2009, two 2010, and one 2013.. And they were great vehicles. BUT. Check the paint carefully. The 2009 and both 2010s paint peeled badly on the hood, back door, and down the sides under the rain gutter. Two we had to have repainted twice. After a lot of pressure and hassle, GM agreed to cover part of the costs, but not nearly all. If you watch while out driving, you will see a lot of white Express vans with bad paint.
