Each individual buyer has a preference, so to assume any 'one' interior version is better than the other isn't practical. Personally I prefer the walk-though simply because I have access to everything without having to open the rear doors. I can also load our two e-bikes in the back of the van between the cabinets on both sides, and still have access to most everything in the Van.
Many of the upgrades offered are viewed as essential to some, but may not be considered important to others,
We have a stove in the van supplied by a propane tank mounted under the drivers side frame rail, but never cook in the van. Having the tank comes in handy though, mainly for powering a Honda generator, and our portable BBQ.
We enjoy the gaucho bench right behind the drivers seat for three reasons;
1. Easily deployed for sleeping two without raising the top (quick stops, boondocking without attracting attention, severe weather)
2. You can sit to read or play on the computer, and still look out the opened barn doors with a relatively wide view.
3. With the gaucho as long as it is, and its seat as low as it is, and the seat-back being much thinner than cabinets - when the top is raised the whole interior feels very 'open' and spacious...especially when you swivel the passenger seat.
Again, just our perspective.
