We do tank fills every 300 miles now with a 26.4 gal OEM tank. Usually we fill at lunch time and again when we put in for a night. not a big deal but sometimes we are forced to pay premium rates for fuel. With 60 gallons of fuel we expect to be able to keep our fuel cost down by $0.50 per gallon. On our Cross Country trips twice a year that saves a bunch of cash. We tow our Subcompact crossover and get 12 to 14 depending on terrain. We just think it might make sense but if cost is too restrictive I can do without. The Sprinter Store wants about $6,000 to do a complete install. That's a no-brain reject cost. If I could do it for $1,000 it would pay off in 5 years. now that I write this I'm not so enthusiastic now.Have you considered the additional weight of the tank....mountings for the tank....and the weight of the fuel you will put in the tank?
Seeing that you have an RV, how much additional weight can you add before you exceed the GAWR of your RV.
Also, are you using the entire 26.4 gallon (100 liter) fuel tank capacity, or do you refill when the low fuel light comes on
with 25% (25 liters....6.604 US Gallons) left in your tank.
What sort of fuel mileage are you achieving and are you driving your Sprinter based V6/5 speed Sprinter in a manner that gets
you the best fuel mileage and longest interval between necessary fuel stops.
If you are getting 15 MPG you would be safe going 375 miles (1.4 gallons left in the tank) between fuel stops.
Guess the real question is why you feel the need to add fuel capacity?

The 20 gallon tank Mr. Wrinklepants mentioned would get close to doubling your range.... Now that I write this I'm not so enthusiastic now.
I’ve the aero transfer tank. I love it and it works flawlessly. But....the gauge is recalcitrant. It won’t regiater a refill whilst in motion, and occasionally not sitting also. I think while parking the pump is too slow, so to get the gauge to reliably register a large quantity needs to be dumped for it to work. At first it anoyed me, buy, now it’s no biggie.The 20 gallon tank Mr. Wrinklepants mentioned would get close to doubling your range.
Transfer of fuel using an electric pump is not an uncommon method for adding fuel capacity. It avoids messing with the OEM fuel system. That said, I don't know how well the MB fuel gauge programming would respond to fuel being added while driving. Use your trip odometer or other reminder.

Sadly the ACGB tank won't work if you have the AMP retractable steps.Just to update this, Agile is now selling the ACGB tank. I see they’ve added it to their website after having a “coming soon” for a tank replacement option.
My 2006 T1N low fuel light comes on when there is about one gallon left. Fillup after that was 25.5 gallons.H

My '02 behaves the same.My 2006 T1N low fuel light comes on when there is about one gallon left. Fillup after that was 25.5 gallons.

Did you wind up buying the tank?Just to add a data point:
I got a quote for the Brown-Davis replacement fuel tank that's 170 liters (~45 gallons).
Including the $800 in freight costs from Australia to Missouri, the quote was $1,618 US.
On the Brown-Davis website, it's part number MBS07R2.
