Personally I would use one of these to see if you really want to spend the $$$.

"IF" I were to do anything I would go with the TITAN 55g for my DRW RAM.

One of the best upgrades I’ve done with my truck was the 60 gallon auxiliary tank. 95 gallons of fuel capacity let’s me stop when and where I want to not where I have to.

But with a short bed I’m not sure I could afford to lose the space. But I also wouldn’t want that tiny tank, so I’d bite the bullet and install one of the 50 gallon replacement tanks.

And no, a 5 gallon portable can isn’t a reasonable substitute for either of the above options. [emoticon]

My last 2 short beds had the tank swapped for the Titan 51 gallon before I even drove it..

The new one will come in with a 48 gallon stock ! ! [emoticon]

Given that we're all about safety here on rvnet, don't you think posting a plastic fuel jug that is not up to OSHA/NFPA standards is a bit risky? Lol

You must have a hell of a bladder! A stop is a stop as far as I am concerned. No I don't care if I spend a few bucks more for a truck stop fill.

I do miss my 35 gallon tank, I know only 3 gallons less now but it makes a difference as I had specific stops along the West Coast. Used the 5 one time as I had not calculated in the long grade from the Columbia River to Yakima, WA.

Bottom line people need to do what works for them. I just think everyone should decide with real world experience before spending BIG $$$.

FWIW, something to consider beyond "when will it run out" and "when do I have to stop for the facilities" is what you're towing and how that impacts where you are when either of the two above criteria kick in.

I had an F350 towing a 39' 5th wheel. Stock tank was (IIRC) 34 gallons. Enough to go as long as was really practical. However, with the biga** trailer, I had to start looking for suitable stations (generally meaning truck stops) at about the 1/2 tank level. This became a real pain the behind, particularly if traveling on secondary roads, and after having to unhook the trailer and run the truck to a station one midnight, it became worth the $$ to add a auxiliary tank.

I went with an in-bed extra 70 gallon tank and it was great. For the next 5-8 years (until the end of the RV chapter of life), I didn't have to stop at all during the "day" but could simply fill up the truck and aux tank once I was stopped for the evening and had parked the trailer.

Wow, I could have written exactly that post. [emoticon] Except my tank is 34 gallons and not 70. And I'm still RVing.

I have an in bed RDS tank I bought used. It really makes it nice. I’m a little paranoid and if my gauge drops below 1/2 I get nervous. Below 1/4 and I’m in a panic. So now just as soon as my gauge drops off from full, I know my auxiliary tank is empty and I only have 28 gallons left. I will usually start looking for fuel when I only have 3/4 of my tank left. This will usually keep me above half and out of the panic zone. Depending on where I’m at, that gives me a range of about 350 miles. If I were to run all the way to empty, I could probably go 550 miles or so. For me to run that low it would have to be a life or death situation.

What year is your RAM? Second gen LB trucks are 35 gallon.

The Titan tanks are really hard to beat, well made and you dont lose any bed space.
