Question: We just purchased a new “toy hauler” RV and we are looking for tips. Is it alright to leave the vents (with covers) open overnight or for a few days at a time with our TV and DVD player inside? We live in Missouri, which has a high humidity rate.
Answer: It should be fine. We have done the same in Florida and in Rhode Island, both with high humidity. It does get humid inside the RV, but it’s a way to get some air flowing when that’s your only choice. When you have poser, shut the vents and run your AC – it will help de-humidify the RV.
