We towed (the major reason we have a truck) with 2 different 1/2 ton Tundras. the Rig weighed 5K. It bogged down and crawled in the mountains. It wouldn't pass a gas station as it would only go about 200 miles before the fuel light came on. It was a great truck, but not enough of one to tow even that modest weight.
We now tow with a 3/4 ton diesel that is so much less hassle to tow with. Refueling is always an issue with us. How crowded is it, will be fit under the canopy, how expensive is it, can we get around the corners, and can we get in without dragging? Larger (much) fuel tanks no give us a 500 mile effective fuel range and fewer fill ups, it pulls with no strain and does so at a much higher speed with lower RPM's. It also is much more stable going down the road if for no other reason than its so much heavier and the weight is more evenly distributed. They are more expensive, but IMHO worth it if you spend a lot of time in your truck.
