Here is my 2 cents on the matter, well more like 2 pesos but anyway...
The Tundra is a fantastic truck. I think on the used truck market it is a much better deal than a Taco too. For the money you are getting alot more truck which to me computes into a no brainer. The 1st gens are indeed larger than the comparable Taco's but they are much tidier sized versus the domestic half tons. I had an '05 Silverado 1500 Crew Cab that I picked up new. My Tundra that I bought used with 140,000 miles rode better, quieter, and was no contest offroad despite the Silverado having the auto locker.
My Tundra is bone stock, I added a cap, built a sleeping platform with storage in the back and called it good. It has served as a daily driver, a tow vehicle (tows my 80 series on a trailer without breaking a sweat), and for doing long trips. I took it to Moab and explored quite a bit of trails and area without issue. I didn't take it on anything terribly difficult as we were there to bike and explore versus wheel but got into places that I wouldn't think a stock truck would fare well with no problems.
One thing to consider is that the double cab Tundras and the access cabs are two totally different vehicles. The double cab IS noticeably bigger than the access cabs. It is obviously longer, but it is taller and wider as well too if I am not mistaken. They have a much deeper bed as well. Some of the feedback so far has not differentiated the size differences. I'd say the acces cabs are closer in size to the new Tacomas, but actually still bigger. The double cab's considerably larger. Just an FYI
I have driven the older Taco's and latest gen as well. The older one's are a bit tight for me, not bad but the roominess of the Tundra interior is more agreeable to me. The newer Tacos are roomier but I lack a bit of the good visibility that you get out of the 1st gen Tundras and Tacos. That said, I think they are all great trucks that can be built to suit your needs. I personally feel the Tundra offers alot more practicality and uses due to it's size and power. If you really are going to be pushing it on the trail in tight, technical situations, you might notice the compromise but it all depends on what you want. As it has been shown in this thread, there are some well built Tundra's that will go most anywhere.
Good luck!
I have stood on the dealers lot and compared the DC and AC Tundras, and the only thing I could tell was that one had four full doors as opposed to the small wing doors. I even scientifically measure the bed with my arms and it appears that the beds are identical in size which was a selling feature for me, because many smaller trucks beds get smaller when the doors are added. Please someone tell me if I am mistaken. Are they totally different trucks?
