I know next to nothing about the Multimatic but I can't imagine it's any worse than the rebuild interval FOX quotes. I don't know if I'll follow it to the letter with my 2.5 and 2.0 IFP since you're supposed to service them every 1,000 miles in 50/50 mixed use. They say 10,000 miles on 100% street use and 500 miles on 100% offroad (which in their definition is probably desert racing type). I wonder if the TRD Pro FOX components have the same intervals? Hmmm.
As far as this truck, if I wasn't a Toyota fanboy who buys only used it would punch all the buttons except for a stick shift. Double lockers, diesel, real tires, reasonable lift from the factory. It's about all you could ask for stock. I honestly hope Ford brings a diesel version to the Ranger and Nissan does something to push the market with the Frontier so that Toyota feels the heat and at least drops in a diesel to the Tacoma. In my view the ideal situation is Toyota just starts selling a Hilux for commercial/base buyers. But that's unlikely.
