Did you mean a 334R"E"? I don't see a 334RL in searches. However, I am not a fan of craning my neck to watch tv, so I am not a fan of RE models.
We have had our Brookstone 2 summers and about 6k miles. No leaks yet.
We had other production issues though, so a thorough going through is a must.
You can see issues about Cedar Creeks here: http://www.forestriverforums.com/forums/f23/
On the same forum you can find issues with Coachmens:

(though very little about Brookstone's).
If you search for forums on virtually any brand, you will run screaming into the night.
