Depending on the space you have to work with, double recliners know as wall hugger models might work for you.
RecPro has some pretty good options. Also, don't just think you can remove the dinette seat boxes to get space. You will need to see what, if anything, is underneath those boxes. It may just be storage, or it may be the water heater protruding into the space and a rather expensive to move, electric power center.
EDIT: it looks like
your trailer was available with a sofa rather than a dinette, so it is most likely a matter of removing the dinette and finding a double recliner to fit in the space, cutting back the LH seat flush with the fridge and making it a shelf or storage area. Me, I like my dinette, could not live without it, but everyone has different preferences.
Suggestion, click on your screen name on the right side of the red bar at the top of the screen (assuming you are using a desktop or laptop) and in the drop down box that will appear is "Signature". If you click that, you can create a personalized signature and include your exact make/model/year RV and tow vehicle. This will enable readers to answer questions more accurately. I frequently look up RV floor plans online when someone asks questions similar to yours, to get a better mental picture of what you want to do. I realize you posted it in the title, but much easier to always have it in the signature.
