2015 forest river solera 24R fuel tank replacement?

[MrE]

Has anyone replaced the stock tank with a 40 gallon S&B tank or any other larger capacity tank?

Seems to be a common upgrade on the overlander type Van conversions. My only concern on a class C is the additional weight. Given the small weight carrying capacity, I'd be hesitant to add another couple hundred pounds for the larger tank and fuel.
