thoughts about increasing the fuel capacity

[WaitingForTheSun]

I just bought a sequoia and realized that Sequoias don't have aftermarket aux fuel tanks like Land Cruisers and 4Runners.
I'm thinking about ripping out the stock exhaust and slap a second factory gas tank on the other side! Then, just run a custom, smaller exhaust in the back.
I think it's totally doable, don't you think?
Another thought was jerry rigging an aux tank from a 4Runner or Land Cruiser (Long Ranger says no way).

I'm imagining a sweet 56 gallon total with balanced weight.
Bonus points if used factory tanks are cheap, and you could maybe even use the stock pumps and stuff.
What do you think, guys? Is this a good idea or a huge mistake?

It's not a mistake, it's a good idea as long as you balance the weight and use toyota stock components. The 4 runner and Land Cruiser tanks can work but the plumbing ans sensors don't always match so it's gonna be a tough job.

the thing is tht I don't have much experience doing all this, my friend usually helped me, but he's moved to another state last week
