Various news outlets have reported that RV sales are suffering because of high gas prices, which makes sense considering the behemoths only get about 6 MPG.

Fortunately, a new breed of RV is allowing passengers (residents?) to float to the next campground. The Terra Wind Amphibious RV turns your motor home into a motorboat.

Keeping the vehicle seaworthy are pontoons and a marine engine. Starting at $850,000, it can handle up to 40 mph winds, and has everything you need while you're rolling down the river, including a refrigerator, a washer/dryer, a whirlpool and an entertainment system. [via Uncrate]
