auxiliary fuel tank for diesel truck

There you go. It's called Peace of Mind.

I stop when I want to and WHERE I want to. No truck stops. No wigglng into a gas station where I may or may not fit. No stopping at a place because it's the only station around. I fill up after I set up my camper. I still make bathroom breaks too. Just not at truck stops.

Do the math - 11 mpg x tank size. Then consider you will want to look for fuel NLT about the 3/4 mark. When both tanks are full on my truck I have at least an 850-900 mile towing range, IF NEEDED.

I got an RDS combo 40 gallon/tool box with gravity feed. Simple is good.

Check Northern Tools for RDS boxes. Or go to the RDS site - they have a zillion different sizes. They really are not all that expensive.

Last - This subject gets discussed all the time here. Just do a search.

Forgot to mention in my first post, I have a folding cover over my bed. More important to me to have locking storage than carrying an extra 1000 pounds for "just in case".

i had considered this also but don't want to take up truck bed space. The only way I would do it is to replace the existing tank with a larger one. besides there's no way my wife not mention my prostate would allow me to travel more than 3-4 hours at one time without a bathroom break so i might as well fill up while I'm there.

I have the larger tank in my signature. I had it installed 8 years ago before I started full timing and it doesn't take any of my bed space. It was $$, but well worth it for me and the flexibility to get fuel when and where I need it. 52 gallons is nice, 26 wasn't.

My truck came with a 90 gallon transfer Flo in the bed and have never fully filled both tanks. Its nice when you find some lower priced fuel and can save money. That being said I don't know if I would actually spend the $1000 plus dollars myself to have one installed. I can only drive for 2 hours before I have to get out and walk so stopping is not an issue and diesel is everywheres..

Why? 300 miles between stops is doable anyplace in the US

Zombie Apocalypse :@

I have a trans flow 75gal in my duramax..wouldent be with out it.

I have one. For reasons other than RVing. But it sure comes in handy when towing. I tow very long distances, through more than one state. It's nice to be able to pick and choose how and when I fill up.

Make sure you put some fuel stabilizer in the tank and/or use it periodically. I do both. Can't go wrong.

Mine is not hooked into the system. Has an external pump. Allows me to fill anything, not just my tank

I have a RDS 80 gal. A ball valve right at the tank and a solenoid valve under the bed. Then into the filler neck. I have a hose from the rollover valve plumbed to the vent line next to the filler neck.

I installed a 60 gallon RDS aux tank within a month of purchasing my new truck. One of the best upgrades I have ever done.

The other thing to me is it saves time during trips. I am a weekend warrior. We often go 200 + miles one way for a weekend. I figure stopping for fuel costs me at least 20 - 30 minutes by the time I figure where I am going to stop, turn off my fridge, get into the station, have my wife walk the dogs, pull out of the station, stop to restart the fridge, get back on the highway and back up to speed. So, if don't have to fill up on the weekend, that gives me 30 more minutes at my destination. 30 minutes doesn't seem like much, until you figure 6 or 8 trips a year, over several years.

When I get my next truck, several years down the road, an aux tank will be a guaranteed addition.
