Should I add transfer tank with factory 34 gal

[jetskier]

I have the 30gallon Transfer Flow toolbox/tank combo. I would do it again even at the $1800 price tag. It's transfers automatically. Toolbox is decent sized. I could have opted for the 50gal version since I have a long bed, but it ate up too much space. The range is awesome. I can go 600-700 when towing . I don't usually go that long without stopping for a break, but at least I don't have to worry about fueling every 350 miles. Empty I can go about 1200-1300 miles between fuel ups on highway trips. 900-1000 for mixed normal driving.


It adds a lot of weight to the truck so you can exceed your GVWR hitched up. I'm over the GVWR a little, but under my axle ratings on the TV.
