In looking at posts by the OP, I don't believe she has posted details about the Sequioa they own. I would suggest that she post more info about the vehicle, especially which engine and whether it has a tow package. I also suggest that the OP heed warnings about the actual weight of a travel trailer.
IF their Sequioa has the 5.7 engine and and it shares the same platform as the Tundra, it may be able to handle up to 7k as long as the TV isn't overloaded with passengers or gear. But I'm just speculating.
Again, the OP has to realize how much heavier a trailer can be when options are added, plus personal gear and water in the tanks.
Those that post concerns about TV capacity are just trying to keep the OP from purchasing a TT that will not tow very well with the Sequioa, and then the OP ends up with the problem of either getting a different tow vehicle or trading in the trailer which can be very costly.
