The tundra with the 600 ACE is a good machine for what you are describing. The current tundra is about 2X the machine that the old tundra was in most every way, if you have experience with them. There was a time that I would have said the same thing as Dan about 2 vs 4 stroke (and I did), but that was several thousand miles ago. We run 2 SWT skandics with the V800 motor, and I've watched another one put on over 12K rough miles before it gave up the ghost. The skandic is big and heavy, and if you get it stuck you best have some tricks up your sleeve, but they do things that I've not seen a lot of sleds do. They get around 20mpg, and will pull like nothing else. If you are going to be hauling weight, that or the bearcat is probably the way to go. Otherwise, the tundra can get even better mileage, is lighter, way more nimble, and the LT version still has tons of flotation.
