Travel Trailers with a rear bed slide... Leaks? Issues?

There are a number of different slide mechanisms but the the way they seal to keep out rain is the same. My rear and side slides have the same rubber seals to keep out water. Also you need to clean off any slide before bringing it in. They all catch leaves, sticks .....As was noted its personal preference to have a slide or not but I wouldn't be afraid of getting one.
