The CVT takes a bit of getting used to. There is a point where it will put the engine up to about 2.5k RPM when you take off and stay there, just try to push the pedal to make it do that. If the RPM starts to drop off then push more. It just takes some getting used to.
They are great vans. 100% made in Japan is a huge plus. My 1996 Toyota T-100, the full sized one before the Tundra is 100% made in Japan as well. It is still going strong. Never once had a problem with it. There is something to say about that!!
