If you want “luxury”, you will need a dually and a TC with slides. Otherwise, you’ll have barely more room than you have now.
You don’t mention how much you want to spend. That’s a big factor. You might also consider a Class C. They do pretty well in snow with the right tires. You can also get a lot more room for less than a big truck/big TC.
A lot of people like dry baths so they can put their snow covered skis and other snow covered equipment inside. I wouldn’t personally want to put snow covered skis in my basement, but then, my basement doesn’t have a slide area, either!
