Auxiliary Fuel Tank Pros/Cons

[colo_dually]

I'm considering running an auxiliary fuel tank in the bed of my dually, and specifically looking at the 98 gallon alluminum unit from Transfer-Flow. I realise the loss of 25" of bed space and the addition of about 840lbs to the truck with this thing filled up. I would appreciate any of ya'lls opinion if these tanks are worth the money, and any problems you have had.

I've managed to put nearly 20k miles on my truck in the last year, and most of that being highway. I'm considering the convience of not stopping as frequently for fuel, and being free to go a little farther to get it cheaper.

I've got a problem, I aint got one

lol but seriously, I hear nothing but good things about transfer tanks, especially in long beds.

I have a 60 gallon with a toolbox on top of it in my truck. I love it. Mine is from Northern Tool, RDS Tank. I was going to get a Transfer Flow but (2) things kept me from it.
1. Cost is much more
2. Only fills the truck when it gets between 3/8 and 1/4 of a tank and I wanted my gauge to move when the tank in the bed is gone.

What ever you decide on I would put a filter on it before it dumps into the main tank. I clogged a filter up after about 60 gallons went through it. Now it has had a filter on it for about a year and is fine.

Not a fan of the transfer style tanks, prefer an actual aux tank instead. Difference is there is a valve and you can select one tank or the other.

I have had Tranfer tanks in my trucks since I was 16 and always will. They are way to useful and handy not to have. It hurts like hell to fill them but have that extra range is so nice.

Which tank did you run in your last truck there, Ryan, and what are you planning to run in your newer F450?

of all my mods my # 1 is the rear detroit, and #2 is the transfer flow toolbox, never failed and i ran it in -40 degree trips up the ALCAN, as of late 115+ degree trips between NV, CA and NM, no issues, allows me to stay on the road as long as I want

I have a Transfer. Been trouble free for the last 4 years. Pulling my 5ver allows a full days drive. The computer takes care of the fuel transfer.

Transfer tanks sound great but if you were worried about bed space then maybe consider a titan tank that fits in where your stock does and gives you more range...just not as much as the other.

I've got the 90 gallon RDS combination tank. The Transfer-Flow was just too much $ to justify for me. The RDS is a simple gravity feed with hardly nothing to break or go wrong with it but it's a slow transfer and it works good. If you use your truck bed a lot you will really miss the extra bed space and you can tell if the tank is full or empty just driving around. You'll have to fill up on the 1st or 15th that's for sure but you'll have time to find the cheapest prices around. I drive about 30 miles out of my way to get fuel at the local reservation and save about 40-50 cents a gallon and only have to fill up once a month. If you get a wider tank make sure the holding tabs don't set on any part of the bed curve, they'll start to crack & break off in 6-12 month, found that out with my old 60 gallon tank. Cost me $100 to get it fixed every year till I got a tank that fix correctly.
