help! I'm new at this... looking for advice.

You purchased a very nice coach and welcome to RV.Net! Hands down the greatest thing I bought for my coach is a dehumidifier It stops all condensation from getting into and rusting out my windshield holder (the holder keeps both your windshields in place) I place mine in my Winnebago between the split windshields. Winnebagos windshields are glued into place so you want to take care of them, if there removed they break and you have to buy a new set. Also when buying items for your coach think light weight!
