Well I've been doing a little bit of searching.
The car is a mercedes-benz SLK class. I can't tell which model specifically. If you go with the bare bones 280 gets you 228 hp 221 ft/lbs of torque and is good for about 18 mpg city 24 highway. All for about $45,000.
Step up to the slk 350 and you get 268 hp 258 ft/lbs 17 city 23 highway and it's $50,000.
Step up to the slk55 AMG and you get 355 hp 376 ft/lbs and fuel mileage is To be announced which lets you know that it's good. All for the bargain price of $64,000
Now the motorhome is more difficult to identify. A little googling and it turns out that you're looking at a Volkner Mobile "Performance". For a company that builds very highend vehicles you would think they could afford a web programmer or two.
Here's some inside pictures incase you just have to have one.

I can't find any fuel usage numbers for any of their models on that page. They do have a model that carries a smart car in the back however.
