Hi Doug,
If you've been looking around new/used really makes no difference, you come to one simple truth. Motorhomes and the floor plans for them are built by crazy people. It's true Doug, they are people who flunked out of engineering school and were offered the only job available to them. You guessed it, designing a motorhome. A strong case can also be made for the owners of these motorhome companies but lets just stay with the engineers for now!
Your observation is correct, kitchen on the patio side, dinette on the drivers side and a couch on both sides. This is also where physicians and surgeons are in cahoots with the engineers because where are the TV's? You got it, one is on the bathroom end of the coach and one is above the dash! No matter the one you choose your neck is going to suffer and off to the doctors you go!
Have you also noticed on the plans where the dinette is on the patio side more times than not its also a bunkhouse plan? Crazy people I tell you, nothin but crazy people! Lets not even get into the people who buy them!
