Is there anything better than loading up the family in your RV and taking off for some fun adventures somewhere across the country? The answer is yes, but only if you have half a million to $2.5 million to spare.

If you do have that kind of ‘spare change' lying around then you too can enjoy one of the top three most expensive RVs. While these may look like other RVs in the traditional sense, the amenities and features offered are anything but typical. Whoever built these super RVs certainly subscribed to the ‘spare no expense' theory. When it comes to comfort and extras, these three offer them all:

1. Vantare Platinum Plus: Coming in at number one, the Vantare Platinum Plus will set you back $2.5 million. It is by far the most expensive RV in the world. This rolling mansion features Swarovski crystal to compliment custom sculptures up top on the ceiling, steps that are made out of marble that lead into the cabin, leather sofas and chairs, and interior room galore. The gas tank can hold 235 gallons which makes for a hefty fill-up, though if you can afford this beauty then the price of gas is probably the last thing on your mind. Best of all the Vantare Platinum Plus has a sports car carrier that is hidden underneath the RV itself. That's right; you can be in tow without having to show it.

2. Country Coach Prevost RV: The silver medal for the most expensive RVs goes to the Country Coach Prevost RV. At $1 million plus, this luxury RV has it all. These are the same bus conversions that you see many of the rock stars and NASCAR starts travelling around in. With room for up to ten people this RV has tons of space and comes with flat screen televisions that are bigger than the ones you would find in a typical American household.

3. Unicat Amerigo Series: Rounding out the top three is the Unicat Amerigo Series. This RV is for all you that want to be able to take your RV off road; seriously. From the outside it looks like an armored truck that is filled with money and on its way to the bank, but on the inside you would be hard pressed to find such luxury elsewhere. At half a million dollars this on and off road RV is not as spacious as the top two but it does have a full kitchen and lots of leg room. This RV can be taken down some pretty rough terrain and allows for its owner to camp in luxury at places where the standard RV would get stuck in a heartbeat. No more hiking necessary.

While there are many RVs that you can choose from if you are in the market, none will offer the comforts, the looks, or the price of these top three most expensive. However, if you can afford one of these ultimate RVs then you will certainly get to enjoy plenty of looks both while at the campground and while on the road to the campground as well.
