Any regrets going with Titan fuel tanks?

[Stab]

My truck will be here soon. I want to install an aux fuel tank in bed ahead of the 5th wheel. It needs to fit under the tonneau cover @ or under bed rail height.

Titan seems to be the only ones with the poly tanks. Which I like but, it seems to me that they could get another 10 gallons on their in-bed tanks by making them more rectangle but, what ever. Anyone used these tanks and are there any cons to using them.

Any other poly tanks out there? I'd like 100 gallons......

I went with a 60 gal RDS Alum tank. I have a soft Truxedo cover and will cover everything. That gives me 95 gal of capacity which is enough for me.
