Kidding aside, can you post the payload capacity that you'll find on the driver side door jamb of your Tundra? This will give insights to your truck's capability.
The rest is a math game. Your trailer will weigh in the 7,100 - 7,600 lb range rolling down the road. This will drop 900+ lbs onto your hitch.
Since you have a bunkhouse, I'll assume at least a family of 4. That's around 550 lbs, fully clothed. Add 50 lbs for the WDH for an even 1,500 lbs. Then add in any pets, wood, bikes, tools, gear, Line-X, accessories, and stuff in or on the truck.
You'll want around 1,700 lbs of payload for that, based on the math above. Just swap out my estimates for real-world figures and you'll be all set. But, it always starts with that payload sticker.
Every time you use an apostrophe to make a word plural, a puppy dies.
