When the 4th generation came out I was dissapointed with 4 things. 1.) Reduce payload, my 4Runner is 1,550 pounds and the 2003 was 1,050.
2.) Towing capacity stayed at 5,000 pounds.
3.) Trunk space is smaller not bigger.
4.) That terrible plastic trim on the base model.
I am not sure why payload is up, but Toyota has changed 3 of the 4 dissapointments by increasing towing capacity, bigger payload and no plastic trim. The trunk is still the same, not too bad, it is like they read my mind.
