Well OP, 12V says you don’t need one, so, sorry, I know your question was not asking our opinion about whether you should get one or not, but he is the salt proclaimed expert on all things RV and Dodge diesel ( and Amsoil…), so you have your answer and the thread is complete.
Lol

PS he will also recommend one of those cheap plastic 5 gal diesel jugs with the enviro friendly spout that takes forever to pour…. That’s all you need for aux fuel…in 12Vworld!

If you are doing back to back to back travel days...sure.

If you stop for 2-3 days between runs, not being limited to truck stops is nice.


Huh?
Would seem easier to get fuel if you were laying over for days because you’d very likely unhook.
Do you unhook every night on back to back driving trips? ( unless something requires you to like too short of site or can’t level up)?
Last thing I’d want to do is unhook just to hook back up 6-8 hours later.

Just be certain to install an “in-line” filter between auxiliary tank and main tank.
I use a 3481 inline filter.
It has threaded fittings on each end so you can adapt to any size hose you use.

What’s the point of that? Do you use an inline filter between the fuel pump nozzle and the filler neck on the OE tank?
Is fuel dirtier if you put it in an aux tank?

FWIW, when I towed a 39' FW, I found the added aux tank (mine was a 65 gallon) was just about the best investment I made for RV'ng. Since we would almost always go out to dinner on overnight stops, never had to worry about stopping for fuel and would just fill up each evening. IIRC, I had (based on stock tank, extra tank, towing mileage) about 1300 miles that I could go between fillups. Made for a very pleasant 5-6-700 mile day, which was about the limit of what I wanted to drive in any case.

OP, my setup is just what you are proposing except my aux tank is 41 gallons. It measures 11" front to rear and sits below the bed rails. I have a bright indicator light that shows when I am transferring. Make sure your electric valve is on an accessory circuit or you may find you are transferring when the truck is off. I have the Fuel Shotz system which is safety float type shut off valve as a backup.

Most of my trips are 100 to 300 miles, we stay a week and return. I don't have to refuel on the road and wait until I'm home for less expensive fuel. After 3 years I figure the tank has paid for itself in fuel savings. From now on out, it is money in my pocket. The tank is a very good add, as I never stress about low fuel on the road.

I have a RDS gravity feed tank. This is my second truck that I have installed it in. Use their installation kit with the check valve. Works perfectly. I would do it again in a heartbeat. Been using it for 10 years.

Grit for the tiny cost of an “in-line” filter and the costly repairs that come with injectors it is a cheap cautionary thing to do.
Regarding filtering from the pumps. From my experience, yes they do sell us dirt. The sooner you catch it the better.
I have filled at some stations where the flow is extremely slow. Why do you think that is? I’d suggest plugged filters drawing **** from the bulk tanks.
All my fuel goes into auxiliary tank.
I have seen dirt right in the fuel line fittings at the injectors on a Duramax.
You can’t be to careful when it comes to the need for clean fuel in today’s trucks.
