That is a luxury motorhome! I see many of them while working at race tracks (occasionally stay in one owned by a colleague), and they are nice! Having the flexibility to take an albeit small home where ever you want whenever you want has advantages and disadvantages.

They are still considered to be real homes when the purchase is financed - you can deduct the interest paid on the loan on your incomes taxes just like a regular home mortgage. You don't necessarily have to find an RV park when traveling just to spend the night (unless you absolutely need hookups). Park it in any Walmart parking lot, and you won't get hassled (at least not by the store). Some are multi-purpose and have an actual garage to house a car separate from the living quarters. You could use that garage space for business equipment and inventory storage, while towing a car behind it to use for getting around town when you're going to park the RV for 3 days, 3 weeks or 3 months. Full hookup parks aren't that expensive (depending on location) which can save you a lot on fuel costs involved in running the generator(s) over operating as a fully self-contained RV. A lot of the better newer coaches have plenty of horsepower, so getting on the highway at speed isn't a concern like it used to be with many land yachts.

Fuels costs are a concern, both for power generation and over-the-road travel. Satellite service for television and/or internet can be expensive as an initial option or a latter add-on. TV satellite automatic tracking isn't cheap, but it isn't real expensive either. Satellite internet automatic tracking is quite a bit more expensive - the tracking system and the dish machinery can cost $8k. Service on just about anything on one of these is going to cost way more than it does than any other vehicle, and the places that can provide the services you might need are much fewer. You can't ever expect one of these to increase in value when looking to sell or trade up to a better/bigger one.

I don't know that you'd save any money over the long run by making such a move, but if a rambling lifestyle is appealing to you, and you can afford it, do it!
