I am the original and current owner a 2006 Tiger, have driven it for 93K miles so far. I am not full-time and it is not my daily driver. See signature for its description. This is my second 4x4 chassis mount RV. Fabulous vehicle for the dirt back roads of the Western US, which I explore whenever possible. I don't deliberately seek out snow, but some Tiger owners do and you can ask them about snow travel.
I am elderly and disabled now (back troubles and very limited walking), but I can still handle the Tiger and all tasks involved in travel with it. It is easy even for me to get from living area to driver's seat via the pass through; I am not sure whether going the other direction (uphill from cab into living area) is possible for me, but a more agile person could do it.
A Tiger with an extended cab can be about 24 feet long; my regular cab model (like La Tortuga in your original post photo) is just under 20 feet. Tigers are currently built on any truck chassis which meets current Tiger factory standards. Sprinter is not one of these. Ram has come and gone over the years; today it is gone. See Specs & Pricing on the webpage for chassis info.
Tigers are wonderful, but their current website is not. You have to dig down with few clues along the way to get to Specs and Pricing.

You don't see new ones around because #1: They are built only on order and #2: They are sold new only from the factory. Once in a while they have one whose deal apparently fell through or which they took as a trade-in, and you'll see those under the Inventory tab on the website. Also, not many Tigers exist. In about 30 years they have produced just over 1300 Tigers. The only model currently in production is the Bengal.
My personal experience and that of many other Tiger folks with contacting the factory is that by phone is best. Currently, they seem to ignore any messages sent from the website form.
There is a Tiger Motorhome Owners group on Facebook. A large percentage of the members are shoppers, not owners. Most participants are helpful and friendly and love their Tigers. As with any group, there are also some whiners. This group is a good source of all sorts of Tiger info and sometimes used Tigers are advertised for sale.
There is another Tiger group on Tapatalk; I find it difficult or annnoying to use and don't go there much any more.
There is a trend in truck campers mounted on flatbed chassis, but most of those have no pass-through. One possibility you might want to investigate is
Phoenix Custom CampersI hope that this info helps you with your search.
