    Anyone care to post their auxiliary tanks or provide any info as to which brand to look into or stay away from. Deezee has a nice black diamond plate combo tank, 43g, 80g or 92g but has a big price tag.

    I have a 74 gallon dual tank from the factory so no tips for an aux tank from me other than its worth every penny when you don't have to stop twice a day for fuel. My 74g will take me 1200 miles bobtail and about 800 miles loaded.
    Don't forget that 1 gallon of diesel is 7 lbs. A 92g aux tank will weigh down your drive axle by nearly 650 lbs. I'd go with 40-50g tops. Hitch weight is 20-25% of the trailer weight. Every lb on the drive axle will steal about 4 lbs from your hitch load which is the issue I am currently dealing with.
     
    Lite bug Thanks this.

    I have a 80 gallon RDS tank. Awesome setup I don’t know how I went three months filling up sometimes three times a day without one. Best investment for a hotshot truck.

    I’ve have seen cab and chassis trucks with cylinder style 100-120 aluminum tanks mounted behind the cab but am not sure how they install them. Those can be picked up for $400-500 from big truck parts places but installation would require a lot of custom fabrication I’m sure. The square diamond plated tanks that you often see mounted in pickup beds are pricey. Around 1500 and that doesn’t even cover installation.

    I would like a bigger tank also but the prices are turning me off. I have a 36 gallon aft mounted tank on my ford cab and chassis and it doesn’t last nearly long enough. There is a 48 gallon drop in tank that I found but even they want $1000 for it. Ehh...maybe. At least installation would be relatively straight forward.

    Yep, they’re pricey. I’d like a combo that I can fit tools in as well. Still doing my research, looks like the guys over at the cummins forum have the rds aux tank.

    Also, gravity fed or pump style?

    So I had to take care a few things now back to this Auxiliary tank. Anyone have any issues with a DOT officer regarding the install of the filler neck?

    Not sure if I’ll get hassled when they see something like this underneath...
