TV aux inbed fuel tank

[Whale1999]

Planning to have an aux fuel tank and transfer system installed in my 2013 chevy duramax dully. I have not decided on the tank type or size. Would like to know who makes the best tank and transfer system?

If you are ordering RDS, you should look at Northern Tool. When I ordered they by far had the best prices.

Just about any truck accessory shop can do the install for you.

Resurrecting old thread as I am considering the 41gal rds tank/tool from camping world using gravity feed with the rds install kit (get cw to install). Wondering if anyone with an lmm duramax truck has one of these using gravity feed and if there are cel codes set in the trucks computer with that setup? I've been looking at transfer flow but they are getting too expensive and any installer other than factory in chico is outrageous on labour - about 2.5 times the out the door cost of the rds setup.

Thanks

I have an aluminum gravity-feed 51 gallon RDS combo fuel tk and tool box in my 09 GMC 2500 D/A. I love the tool storage in the upper part, as well as the xtra 51 gallon capacity if needed. Just finished an 8000 mi trip through 13 states. This tank works great, no need to invest xtra in a pump (that someone may decide they need more than you). I Purch this tank from Northern Tool for approx $650 total several years ago.
.....To the others who are having trouble with slow drainage, check the breather tube that is connected to outlet of valve, mine had a dirt-daubber nest in the bend of the tube that I could not see, (until I removed the tube). I now screw a cap over the line when I finish draining. I fills my truck faster than I burn.

I like that. Where did you get it? Presumably not Italy...

I have the RDS 40 gallon tank/toolbox combo, giving me 78 gallons in total. I think RDS gives you the best bang for your buck. Yes, the hose that runs to the OEM fuel line is small but I don 't care. I keep the valve closed while driving and then flip it open when I stop for the night, then flip closed again in the morning. It refills the OEM tank overnight.

Also, like others have stated, I go fill up after I have set up at the campground. Much easier and I usually combine the trip with a dinner or grocery run. The extra tank allows me to buy fuel when I want to, not when I have to.

If I had it to do over, I would get the 60 gallon tank/toolbox combo. The footprint is exactly the same, but with a smaller toolbox.

I have a 60gal RDS gravity flo tank. That gives me 95 gallons when everything is full. The tank allows me to buy fuel where and when I want and that is really nice on a long trip. I could go on but I have been very happy with this set up for half the cost of some other tanks.

I have an older 2006 with an 45gallon plus toolbox combo. It is gravity feed based system and works fine and keeps up with the consumption on the road. The only time it seems to tick off the gauges is if I dont shut down during stops. But since I stop ever 3-4 hours driving for a leg streach and restroom break it resets and doesnt really become an issue.

With the stock tank I could easilly make the same stops and get fuel while I am at it, the reason I found I can justify the tank is two fold. I can skip the more expensive states by planning out my fuel stops, sometimes saving as much as 30c a gallon.

I have also found that now that im just over a month from my FL vacation departure that I turn off the top tank and have started topping the truck off once a week (dont drive it much during the week) and put the rest of the preauth ammount into the tank. By the end of the month when I am in final prep for departure I wont have to go and buy 40+ gallongs of fuel.

Lots of folks on this site will try to talk you out of an aux tank. I feel my RDS was one of the best mods I have done on the truck. Having extra fuel capacity doesn't mean you can't stop when you want to. But it does give you the ability to choose where you stop. With 96 gallon capacity, I never have to stop for fuel during our typical weekend trips. On longer trips we can stop at rest stops to use the restroom, walk the dogs, take a break from driving. Much nicer to do that than be forced to stop at a truck stop.

This.
Like Bionic Man says, it is much more enjoyable to stop at a rest area for restroom, walk the four legged kid(s), and take a break from driving, I have to stop just once a day for fuel now.

75 gallon Transfer flo in my Dodge. No issues other than the inline filter mounted on top of the tank likes to freeze up in the winter. I keep a few spare filters and a jug of Diesel 911 in the truck at all times. If you do any amount of travelling the cost of the tank is recouped quickly IMHO. I live in Nova Scotia where diesel is approx. $5.38 / gallon. I filled in Indiana on Friday for $.3.79 / gallon....that's $175 cheaper than filling up here at home.

You don't have to spend $1500-$1700. I have a manual fill 40 gallon tank with a hose and pump, total cost around $500. With the stock tank of 35 gallons I can now fill up once a day. And the wonderful part is that I get to decide when I'll fill up. Like the man says, you still don't have to drive until you're empty, but you don't end up taking your breaks in a noisy, stinky truck stop because it was no problem getting fuel while hooked up.

I usually fill up in the evening after we've stopped for the day and have unhooked. Now I don't have to worry about finding a station that will allow me to get in and out with a 40' toyhauler. It's not a big deal if you stay on the interstates and major highways, but get off the main routes and easy-access stations can be harder to find.

That is the reason I have my aux tank. I never worry about range and can fill at easy access fuel stops. No regrets on my purchase.
