For your 2020 Toyota Tundra Crewmax 4WD, I recommend the SumoSprings Solo Custom Helper Springs item # SSR-610-47. These are the 1,500 lbs capacity springs and which will still give you more than enough support for your 7,394 lbs travel trailer.

By my math you could be somewhere between 740 lbs to 1,110 lbs of tongue weight if you follow the 10% -15% of your total trailer weight formula. This means the 1,500 lbs capacity item # SSR-610-47 are perfect for your set up. The Item # SSR-610-54 have a 2,800 lbs capacity, which you will never use, so this will save you a few dollars.

SumoSprings use progressive load control which means the springs compress according to the weight of your cargo. When you are driving. Unless your suspension is worn out you will not even notice there are there when you are not towing or hauling a heavy load.

I have linked a picture below along with an installation video so you can see what they look like when installed and understand the installation process. You will need to remove your factory bump stops.
