So this product works as intended but is not a good idea for someone towing a camper van. You may or may not want to be exactly on the same level. You may need more or less air to get the ride you want. Also, hitching up your truck when unloading will make it difficult to hitch up in our experience. In short, the fact that you can't adjust the pressure is what really causes the problem. I removed mine and replaced it with a wireless air model.
