Well, you've done a bunch of "bench" number crunching and actually took the combo out on the road in some less than ideal weather conditions (windy) and you felt the trailer behind you, but that's to be expected... I feel my little 22' TT behind my F150 with it's windy out... ;)
Too bad you didn't find any scales to drive it over, as that would give you some real numbers to crunch...
The decision really rests in your hands now... There was another member on here that used to have an Armada, which is similar to your Sequoia in terms of WB and tow ratings I believe.. He ran with that combo for a couple of years and spent additional $$ trying to make it work, but in the end, he traded it for an F250 I think it was... ;)
He did all the number crunching too and on the "bench" it looked like it would work.. In the real world and after a couple of towing seasons under his belt, he made a new decision..
Anyway, I may not have gotten all the details correct, and won't say one way or the other what YOU should do... Just wanted to rely the story if the other member does not see this post..
Good luck no matter what you end up doing!
Mitch
