We both drove, taking turns constantly to stay comfortable with it. We both know how to do all the connections to the RV and the towed vehicle.
We don't understand why women think they can't do it. They drive cars just like men do. Men and women have the same skills with a car. You don't need to be a big strong guy to drive a RV. There's no strength involved. Yes, the first few times are tense - for BOTH men and women - even if the guy doesn't say so. However, the more you do it the more comfortable it is. Don't just drive it a few times and say "I can drive it". You need to keep up with it. If you don't know the steps to take, make some cards and keep them by the dash.
As far as selling a RV - the best would be to have a relative or close friend help you. You could also take it to a consignment - PPL in Houston is good - then there would be no hassles in selling it.
Things have a way of working out when the time comes. Deal with one thing at a time.
