For towing a 100. I get by with my 80 and the camper but its not fast. That said personally I like the ride of an 80 better. Its more truck like which is what I prefer. I like the seats better too.
You could consider a 1st gen Sequoia too. Not as nice on the trail but for everything else good. And cheaper to buy. Most Tundra stuff will fit.
