Class B RV
You get both the truck and the home in a Class B RV. It looks like a very large van. Here you have the transportability of your family's van or SUV plus the amenities of home. Much easier to drive than the trailer options, you can park with a modicum of difficulty and have access to smaller roads that would be impossible to pass with a larger RV. Much faster to drive, these vehicles get better gas mileage and when the engine gives you problems, the parts and mechanics are easier to find.
The interior is tiny though and suited for one or two people. This space limitation makes it the most expensive per square foot than other RVs and its appliances must be small, making them difficult and expensive to replace. And when you show up at the campground, the price is usually the same as the larger motorhomes.
