I have a 2012 Tioga Ranger 31n, and have been very happy with the floor plan, especially after I took out the dinette and put in my old, comfy leather recliner! It is big enough for full-timing that I don't feel cramped.
I remember when I first saw mine in a showroom, it looked enormously HUGE, and I thought I could never drive it, but I have put on 60,000 miles in the past three years! Have not hit any humans or animals, although I do admit to grazing a post pulling out of a site once and backing "gently" into a telephone once and bending my bike rack! You just have to use your mirrors, as everyone told me, and get out and look a lot when you are backing up.
Actually, I was terrified of changing lanes, so it took me a couple of months before I passed anyone! I still am very careful about checking mirrors before changing lanes. If you put your turn signal on, most people will give you room. Truckers are pretty good about letting you in, so I am careful to also let them in. My biggest problem is not going into something like a parking lot I cannot get out of, so I check very carefully for an exit before I enter. Does that make sense?
Also, remember that you have steel bumpers front and rear, while all those little cars have those plastic ones! I feel like putting a big sign on the back of my motorhome that reminds them I am bigger than they are and not to cut me off! I am constantly amazed at how many people try to pass me on an entrance ramp.
