Looking at your floor plan, that slide out is designed to hold a small couch (love seat) and a booth dinette. If your's came with a stand alone kitchen and chairs, or you can easily remove the booth, then placing two recliners there won't hurt anything as far as weight goes.

In a previous camper, we replaced the stand alone kitchen table and chairs and 2 recliners with a true house hold 3 seater recliner couch. It was heavy. We never had any problems with the slide out.

You'll be fine. That's the nice thing about having movable furnature. You can put it wherever you want, or RE-move it completely if you want and RE-place with something else. (or nothing).
