Larger gas tank?

I’m looking to upgrade/get a bigger gas tank for my 04 Tacoma. It’s a v6 prerunner if that changes anything. I’ve seen some that are 60 gallons but I feel like that’s a lot. Is there like around 30 gallons? I haven’t found any around 30. I don’t really want to drop around $1,000 for a 60 gallon gas tank. Any help or suggestions?

 

How do you make it fit? Do you have to take off the bed of the truck? And what year?

 

Made for a tacoma is ~35 gallons and over $2 grand. Carry 3 Gerry cans or a marine tank and a transfer pump if you don’t want to mess with a funnel. $200 all in for the extra 15 gallons.
