OP, can you get to the kitchen when the front slide is in?
I like most everything except for the lack of outside storage. I have more on my 28' 5er. As far as the tanks go, I doubt too many would dry camp with that behemoth. At almost 41' long and with a Res fridge you'd have to have a big site and a large battery bank, or solar and or generator.
We can easily go 4 nights with our 54-40-40 tanks. I could see going 5-6 with that FK unit.
Lots of pro's and cons. We're not the RV park types so we'd probably pass on it.
To the OP, Happy Camping.
