Hi, papapump13, and
Lots of folks make "refueling" tanks that are hauled in the bed of the pickup. It's illegal to hook them up to have automatic flow of gas into the stock tank, but you can use a hand pump or a battery-powered pump that's legal to pump gasoline, to do that job yourself. (Diesel can be gravity-flowed into the stock tank, but not the more volatile gasoline.) An installed refueling tank is a lot safer than hauling gas cans in the bed.
If your Tundra is a regular cab, then you probably won't find a bigger replacement gas tank, so your only option is probably a refueling tank.
Here's a big refueling tank, complete with electric pump and hose to transfer the gasoline to other vehicles, or to your pickup's stock gas tank:
82 Gallon Refueling Tank System
82 gallons of gas weighs over 500 pounds, so be sure your Toy has enough payload to haul that much gas plus the hitch weight of the trailer without being overloaded.
Here's another refueling system that costs a bit more money:
50/50 Gallon Split Refueling Tank System
Yep. Not cheap! But when looking at other brands, first be sure the tank is legal for gasoline, and then be sure it includes the pump and hose to transfer the gas to your stock tank.
But if your Tundra is a doublecab or crewcab, and you don't want a refueling tank in the bed, at least one outfit makes larger replacement tanks for most doublecab or crewcab Tundras. TransferFlow is an excellent choice for a 46-gallon replacement tank if your Tundra is a doublecab or crewcab. That probably more than doubles your gas tank capacity. Not cheap, but really excellent products. I checked for one for a 2010 Tundra Limited CrewMax 6.5' bed 4x4, and for a 2010 base trim 4x2 double cab with 6.5' bed, and here's the one they said would fit:
46 Gallon Midship Replacement Tank - Transfer Flow, Inc. - Aftermarket Fuel Tank Systems
If you don't have a 2010 Tundra Limited CrewMax 6.5' bed 4x4, or 2010 doublecab 4x2, then play around on the TransferFlow website and see if they make a replacement gas tank for your Tundra. I couldn't fine one for a regular cab, but they make them for DoubleCabs and CrewCabs.
My F-150 came with a 26-gallon tank, which was good for only 200 miles when towing heavy and getting about 8 MPG. So I replaced it with the OEM 36-gallon tank. Everything fit fine, and the truck's "miles to empty" computer is accurate, but it cost me over $1,000 out the door. Now I can go up to about 280 miles before I have to buy gas. But if I had a 46-gallon tank from TransferFlow, I could make it over 350 miles when towing before I had to worry about a gas station.
