We always vent thru windows and or top hatch. We had moisture even under mattress prior to learning the venting thing. Do check under mattress if you have not done so.
Definitely check under your mattress for dampness (and mold). We ended up buying a product called hyper-vent and putting it under the mattress to be on the safe side. It is a type of plastic mesh that allows air to pass through it and eliminates hot mattress resting on cold roof platform over truck cab and creating condensation that is absorbed by the mattress.. Well worth the money in our opinion.
