I never noticed any issues on our 2010 Sequoia tranny hunting or struggling to keep moderate power climbing the ascents while towing our TT loaded weight at 8300 lbs (RV park stays with less loaded weight). It was the short wheel base being pushed around by the much heavier and longer trailer especially when it came to descents. Yes, I am very familiar with gearing down on descents and properly setting up our WDH but it just-didn't-help. The Sequoia platform would be perfectly suited to a GVWR trailer below 7000 lbs. The towing specs on the 2010 Sequoia is a flat out lie and that statement can be supported by comparing the 2010 model to the 2011 Sequoia.
We still have our 2010 Sequoia. It wasn't cheap and it still feels like it is new but I've been pretty disappointed with some of the engineering aspects of that vehicle. For the most part, it is a very good vehicle, just falls flat in certain areas. Toyota could have done much better with regards to engineering value.
