Ron why do you say this?"We own a 2007 2350 purchased new back then. No doubt, the tight bathroom and rear corner double bed are confining. It does seem that many people find them tolerable until after they explore a larger model like the 2552. I can understand the 2350 would be especially an issue for people with limited mobility."What mobility issues? Some of us just don't like climbing over each other to get up in the middle of the night. Or in my case my wife does not like closed spaces. We both gave up our teddy bears many years ago and don't feel the need to "have to always sleep together in the same bed".
