I am in favor of the trailer and bike option. I agree paid for is the best option of any vehicle. On that note, if you must have a truck, i would look at the 1st gen Tundras. Here is why. For the purposes of the comparison I used an '05 Tundra, and a '10 Tacoma in both Short bed and Long bed. I chose the '10 Taco because I assumed most gen 2 Tacos are very close. I chose the 1st gen Tundra, because I am not really a fan of the 2nd Gen Tundras and the gen 1 Tundras are closer in size to the 2nd gen Tacos. Where there is not data for the long bed Taco it is the same as the short bed. All of his information and more may be found @ cars.com.
EDIT: This had nice easy to read columns until I posted it. Hope that it is clear enough.

The power and torque is in the Tundra's favor. The fuel economy is almost identical slightly favoring the Tundra in the city. However, mileage between fill ups would be in favor of the Tundra due to its larger fuel tank (out in BFE this would be very important). Payload and towing goes to the Tundra. The size differences between the two trucks are just a few inches in all directions. However the size differences translate to the Tundra having a larger more comfortable interior and larger bed. While the Tacoma short bed would be more nimble in town and off-road, the long bed will have a worse breakover angle than the Tundra because of its lower ground clearance and almost identical wheelbase. These are the reasons why I chose a 1st. gen. Tundra DC. The numbers are even better for my needs when compared to a 1st gen. Tacoma DC which is what I really really wanted.
