Hi, I looked up the Pleasure - way Excel TS just using a web search. From what I can tell, the Excel looks like it is based on a Ford Van chassis, not a MB Sprinter. It is also not listed on their web site anymore.
There is a Plateau TS model - Is this the model you are thinking about?

Some of the information on the web site about the based vehicle is incorrect, but perhaps that does not matter. For instance, it talks about the engine being 3.6 liters. At least in the US, the two engine options are 2.1 liters and 3 liters, and I am thinking that this is true for all North America models.
The 3 liter / 6 cylinder engine comes with a 5 speed transmission and the 2.1 liter / 4 cylinder comes with the 7 speed, unlike what their front site indicates. It is a traditional trade off of power to climb a hill vs fuel economy.
Rust is a common problem on Sprinters unfortunately, especially if they have been dented or exposed to ocean air. If you buy it, don't delay to get that rust repaired right away or it will just keep spreading.
If I had to bet, I would guess that they took it up a steep driveway hill and scraped bottom, denting the tail pipe and mashing a few things, loosening up the fridge as well. This probably prompted them to replace it with something that has more clearance.
A class B size is good for 1 - 2 people, maybe 3. If you have 2 adults and a couple of kids, it is tight if everyone plans to sleep inside. The RV + a tent can work out well.
