think if I bought a new one I think I'd have them turn the shitter into a closet. I don't need a can or a shower, it seems kinda ridiculous in the model I'm looking at anyway. I just need someplace dry/cool to sleep, and the ability to make breakfast in the morning would be sweet. Plus someplace to hide from you heathens when the rain is on. Nothing worse than a building packed full of stinky wet sailors.
Triple stacked with my pickup about the best I can expect is 15mpg, at worst I think I've seen mid-10's, typically I'm around 13-14mpg doing 72mph and I constantly use the cruise control, but that's with a proper transmission, not some automatical, and thats with ~600 ft/lbs of torque at the wheels. The worst mileage I've ever gotten period was coming north through illinois with about a 40mph headwind with a large safe in the box of the pickup, a 24' enclosed trailer, and about 25k lbs gross weight. I was down around 7mpg. That frickin sucked!
