Hi Sarz272000 Ron,
Our PC is a 2007 2350. We have owned it for 9 years now. We special ordered ours and did consider getting the HDH type of leveling jacks. Given they are added after the rig is complete, I figured....."Why not do without them, save the money and the weight, and see how it goes? If we later determined that we want them, we'll get them installed." Nine years later and we still don't have them. If someone waved a magic wand and they suddenly appeared on our PC, I would welcome them. But we have been doing fine with the Lynx leveling blocks, chocks, and top caps. They are very light weight and store nicely in our 2350 outdoor storage compartment. We travel exclusively in national parks and other federal lands where the parking pad is rarely level and often uneven. Even so, more often than not, I am able to get the rig "level enough" by looking at the bubble levels I stuck on the dash and door by the driver, and work with the uneven parking pad. As mentioned by randallandchris, we try to park with a slight downward slope towards the front to keep our heads higher.
About the 2350 rear corner double bed. It's smaller than a double bed at home and is not for everyone. My wife and I are now in our late 50's and it is working okay for us. My wife is 5'-1" & 120 pounds, me at 5'-11" & 180 pounds. My point here is that we are not big people. If either of us gained 40 pounds, we might have a problem. I do wonder at times if it would have been better to have the shirt closet over the bed to be made more shallow to match the depth of the rest of the cabinets over the bed. Having it so would make it easier for the person by the window to get in and out from the bed. I did mount a television on that shirt closet which makes matters worse yet, but we like having a TV in the bedroom. I figure if in our later years we are having a lot of trouble crawling in and out from the corner bed, we'll get rid of the TV and make the shirt closet more shallow.
You can request a 3rd matching pedestal-mount captain seat with seat belt today in place of the Euro chair and it might not cost extra. You CANNOT have a seat belt for the Euro chair because of the way the chair is temporarily mounted via a clamp to hold it in place while in transit. Back in 2007, a pedestal-mount low back barrel chair with a seat belt came standard. Some years later, I bought a 3rd matching captain seat to replace it for comfort and safety. The seat belt is mounted to the pedestal, not the seat, making it very simple to change seats.
The NO-slide dinette 2350 comes with 4 seat belts, 2 per bench. So our 2350
HERE has 7 seat belts. A slide out with the couch and 3rd captain seat, you get 5 seat belts.
Regarding upgrading the suspension, you can't go overboard with improvements like heavy duty stabilizer bars, rear trac bar, better shocks and steering stabilizer. The E350 chassis 2007 and older were real bad because they came without a rear stabilizer bar. The 2008-2016 are better but it is a matter of personal preference as to whether it's good enough. Each owner has their own thoughts about that.
As far as the rear end sag is concerned, the 2350 is typically built on an E350 chassis which does sag a little when carrying a full tank of fresh water and empty waste tanks as shown in this picture of our rig on a trip. Keep in-mind our E350 is a 2007 model year. A 2008 to current day E350 sags less for the chassis CCC was increased in the rear axle by 700 pounds. Helping further, the fresh water tank was relocated more forward and more toward the center side-to-side. I assume the rear end sag goes away with an E450 but then you deal with an extremely rough ride. I personally feel there is no issue with the E350 sag for it is not much. Shown here is our 2007 E350 chassis with a 2350 NO-slide on it's back. Our 2007 chassis would sag more with a current-day 500-600 pound slide out.....and more yet with HDH levelers. If contemplating a 2351, I would consider an E450 chassis.
