Some are OK with cutting it close or trying to precisely match payload. Many have decided to step it up to have more than ample payload so they can add cargo or go to a larger trailer without payload concerns.

I have an RDS 45 gallon tank. Fits against the cab and only take up 10” of bed space, doesn’t extend much above the sides of the bed either. Mine is gravity flow into my main tank. I’m a little paranoid about running out of gas and I get nervous when my needle goes below half on the gauge. True panic sets in at 1/4 tank. The extra capacity helps to ease my mind.

I enjoy stopping at rest areas and travel centers more than truck stops, so I also have more options there. Most of the time I buy fuel while out and about and don’t have to when the trailer is attached.

My next truck will also have a larger than factory tank, maybe in bed, maybe a titan.

I have had one with the tank and tool box. Gravity fed, It was nice, but I had to have CPR a couple of times due to the sticker shock from filling up.

I have a 35 gallon tank in the bed of my Dodge dually and simply love it. Best money I've ever spent on something that wasn't motorcycle related.

I love that I don't have to check out the fuel stations ahead of time to make sure I can get in, and, more importantly out, with that 40' toyhauler in tow. I can carry enough fuel to only have to fill up at the end of the day when the 5th wheel is not hooked up. Lowers the daily stress level considerably, especially if you're traveling the two lane highways with fewer big ol' truck stops.

I like taking breaks at rest stops, or parks rather than using the fuel stop as break time.

I like being on my schedule rather than the trucks fuel tank's schedule.

Okay, the cons...uh...well...hmm...it does cost more when I fill both tanks.


^^^ x 2 (or 3). Had an in-bed tank on my F350, then got another 350 after the first one was stolen.

I got the tanks from American Tank (??) in Frisco Texas. Got a 60 gallon tank the first time; 2nd go-around was a 40-is gallon with toolbox top. FWIW, the toolbox top was great, but it couldn't hold my tools and "stuff" (lube, air chuck, etc), so I had to carry another container of tools-n-stuff anyway.

I did the plumb-it-into-the-system route; ended up with a in-dash switch that changed the feed and the gauge read between the factory tank and the aux tank. I really liked the setup and really liked having a 1000+ mile range between fillups...allowing fillup after dropping the 39' FW in the evening.

They do take bed space but I was towing a FW anyway, so the bed was mostly shot for any significant hauling. I had the shop do the install for me...that was another $125 or so back in the day.

...and of course, if one fills both the factory tank and the aux tank at the same time, your bankcard will whimper a bit. [emoticon]

60 gallon RDS tank. This is my second one (different trucks).

First one was gravity fed. For the second one, I opted to use a 12V pump connected to one of my upfitter switches to feed the diesel through a fuel/water filter/separator first on the way to the tank. As a bonus, I can do it all from the cab.

I can't remember the last time I filled up with the RV, or paid exorbitant truck stop prices. I get to shop around and get fuel when and where I want.

I used to have 50gal Transferflow with attached pump/nozzle. It worked ok, but I much prefer the 100gal on board now.

Soon after 9/11 I couldn't drive over the Hoover dam with it.

On top of that, I am going to put helium in the tires.[emoticon]
