We had a FR Sandpiper 366FL, wife loved it, I hated it. Very little basement storage and you sat 90° to the television. It did allow for a nice sleeping area for our kids at the time. We are now in a rear living room model which I like but we both miss the room of the FL.
We looked at the Cardinal FL and really liked it but could not make a deal on it. The Cardinal has 2 couches across from each other a love seat facing the TV, 8 people could actually sit in the living room. The wife also loves the kitchen. I'm sure our next unit will be a FL but hopefully that will be a coupe of years away.
One more thing, these units can be heavy with a low CCC so make sure you check this out. The Cardinal has 8000 lb axle options.
