The topic of best brand comes up A LOT.
Here is the search for "best travel trailer brand" only from this site and limited to the last three years since quality changes a lot over time.
The results vary in usefulness so you may end up having to make a new post to ask with your specific needs listed.
Finding a travel trailer that sleeps 6-8 (or more) on paper is easy.
Finding a travel trailer that sleeps 6-8 without most of them sleeping together and crowding into each other during the day (especially rainy days) and getting in each others way at the limited facilities (or overloading them) gets much more complicated.
Its good you are "close knit", hopefully nobody snores loudly.
With a travel trailer that big (and optioned with stuff like slide outs) keep an eye not just on the overall weight of the trailer but also your tongue weight if you are bumper pulling. It can be hard to figure out exactly what the tongue weight of a specific model is when fully loaded since they have so many options and usually only list dry weight (no equipment loaded or tanks filled).
It would take some looking up of numbers to find out what your specific Tundra as equipped can handle max for pulling overall trailer weight and tongue weight on the bumper hitch.
There is extra equipment you can add to make it handle the bumper weight more gracefully but weight limits are weight limits.
That might narrow your options down so its probably good to figure that out first.
