Oh they hold there value thats for sure. I had the four door, auto V6 Tacoma TRD package and it was great, I sold it cause I needed a bigger truck for towing and especially for the larger PU bed in the back.
As for towing large items I towed my 21 foot Jayco trailer which weighs about 5000 lbs several times up to NY into the mountains to hunt.
It did it, it worked but I don't care what the rating is it was not good. It worked too hard, the brakes are too small and the biggest problem was wheel base. You need a longer wheel base and bigger brakes to handle that kind of weight safely.
Thats the key word safely.
Cy if you are towing regulary then get the V6 like Chum said, the four will do it but it will be a work out for it. The Toyota trucks are sort of like the Yamaha marine engines, they don't make the most power but they last a long time and are not stressed or tweeked to get that little extra ummph so if you want to tow get the V6
