We have a 2351 with the corner bed, I'm 5'9" 160 lbs and my wife is 5'8" 133 lbs. We both are very comfortable in the bed, we did upgrade the mattress to include the gel foam layer. We also opened up the bathroom, removed the wall back to the shower, moved the toilet to the outside wall and eliminated the door enclosure to the bathroom. This opened up the bed some and made the space much more comfortable and it easier to make the bed. We've had our unit since the middle of August and have spent about 8 weeks in it. We travel 6-8 weeks at a time 4 times a year so we spend a lot of time in that bed. We are VERY happy with it so far and don't feel it will be an issue. My wife sleeps on the inside, she has a urostomy so she doesn't have to get up at night and that makes it easier for the two of us to coexist in the bed. I get the side close to the toilet so I don't wake her up when I have to get up.
