If you have no use for the extra camper now, just sell it and be done with it. Renting it out is a very, very, very bad idea. Not everyone thinks like you do, and probably first time out, it will come back destroyed! Oh, you'll keep the deposit for sure! But it will cost you many times over the deposit to fix the camper, just so you can THEN sell it!
Get rid of it now while you can and keep the wife happy! That camper will always be a source of irritation to your wife, and next thing you know ... well ... now thinking about it, you may want to keep it after all. You may find yourself sleeping in it alone!
