We did the Titan 55 gallon tank in our 2016 Ram 3500 dually and wish we had done it sooner. No more worrying about trying to fuel up with the 42' long 5th wheel attached. I went with the kevlar shield to go under it as well, just in case, since it hangs down about 1-1/2" lower than the 32 gallon OEM tank. I like it because it lets me keep my 8' long bed unobstructed. Plus keep in mind diesel is 8.3 pounds per gallon, so your GVWR or load on your rear axle can be affected by going with 75-100 gallon tanks in the rear of your bed. Plus I like having the CG lower with the fuel under the truck rather than sitting up higher, since the 5th wheels already like to wag us around a little!
