How about this!

Check out the 'Terra Wind' amphibious motorhome designed by John Giljam. 
The 42-foot luxury motor home features a kitchen, plasma TV, bathtub, king-sized bed and huge inflatable pontoons that pop out of the sides of the vehicle to keep it afloat plus marine transmission for propulsion in the water.
