Larger than oem fuel tank ?

[pickeljr]

The isata 3 fuel tank seems small for any distance traveling. So I inquired about a larger tank availability [emoji32]. I was told that the tank size for the sprinter chassis was designed smaller because the chassis is usually designed for a van usage ? So there wasn’t a need for long distance vs around town usage.
So my question to the world of aftermarket genius’s is there one being designed or available ? I hate to carry fuel cans.

They’re very expensive. Look up on internet by typing in sprinter van after market fuel tanks. Also I think I read some where it can void your warranty. I use two no spill diesel cans.
