This May Be The Heaviest Duty Motorhome In History. Check It Out.

We’ve seen some bad ass motorhomes, but this one may take the cake. If you know of one more heavy duty than this, we want to see it, because we think this might be the heaviest duty motorhome in history. This 8×8 HEMTT Expedition Vehicle only gets 4mpg, but it just might be worth it for a motorhome that has 450 horsepower and 52 inch tires. What’s cool about this thing is that the builder took the original 8×8 and slapped a 25 foot toyhauler trailer on the back, then Baja and Glamis tested it. I am sure that Oshkosh never thought this would happen to one when they designed it. I’m also sure that Brian is nutting himself checking it out right now.

Here is all the info from the seller. We want it!
