Is a travel trailer with a slide out a good idea for me?

I'll agree with that many people a slideout is a must-have. I'll disagree that there problem free. I've had two slideouts that had water intrusion issue. My only advice is to be diligent on maintenance. Both units had the aluminum strip at the bottom of the sides let water in. The vinyl had shrunk in the strip and let water pass by the screws into the floor. Both of these units were purchased used and could be attributed to lack of maintenance.
