I think I need to publish my campground list of places we've stayed with our 40' motorhome - public campgrounds, not RV parks. I have 300+ word processing pages full of parks. :)
If 35'/36' is what you feel you'd be comfortable in then get it. You'll find very nice places to stay, including national forest campgrounds, our favorite. Since you enjoy public parks many times you won't have hookups so you'll want large holding tanks, for sure.
Since we enjoy national forest campgrounds they typically are in a forest. We purposely chose and ordered our RVs with only two slides and both on the driver's side. It's hard to maneuver a RV, especially if you're single, inbetween trees so that you can open the slides. Having only two and on the same side made it super easy for us. We had the bedroom slide and a long living room/kitchen table area slide.
A table rather than a booth is great. You can use the chairs elsewhere if you have guests and they are much more comfortable on your back than a booth bench.
We don't watch T.V. so that wasn't an issue for us and we didn't want a washer/dryer. When you're using public campgrounds without hookups the washer/dryer makes no sense. Besides, we went into town for errands and 1-1/2 hour of the laundry and then we didn't have to think about laundry for a couple weeks. (Buy lots of underwear) :) You don't have to change outer clothes daily.
Recliners were a must for us and the Queen bed was just fine.
Everyone is different. You'll just have to put your 'wants' on paper and see what kind of RV you can come up with. Good luck!
