Auxiliary gas tank

I have a Chevy 2500 gasser with a 26-gal tank and get about 7 mpg towing my 35' 5er. As you can imagine, having to refuel every 150 miles is quite tedious, especially because I don't have a lot of experience backing a 5er in tight gas station lots and can't use the truck islands. I have a 5 gal gas can in my bed that I can use if I just can't maneuver in a station and am not comfortable driving to another one. I have not used it yet, but I imagine filling up with 4-5 loads would be tiresome and time consuming.

I think replacement gas tank may be too expensive and this is really a daily driver with camping every other weekend planned, so probably unnecessary. A removable can seems most appropriate.

I came across 14 and 25 gallon gas carts that seem to be DOT rated on AmazonAmazon (http://a.co/9u25OPk) and wondered what folks here thought of them?

Do they fit and hold up in your truck bed with 5er attached? How do you anchor them? I hear they take forever to empty and might have low quality valves. Maybe a couple 5 gal cans are the solution. Any other thoughts?

  • I put a 50 gal replacement tank on my F250 and I use it as a daily driver. I generally can drive over 500 miles towing my TT, so I only have to fill up once in the morning and I'm good all day. As a daily driver, I can generally go 4 to 6 weeks between fill ups - that's priceless. Next truck I buy a 50 gal replacement tank will be the first mod, second will be the spray on bed liner.
  • My 2005 chevy has the 26 gallon tank also. I try to fill up at a 1/4 of a tank so around 200 miles between gas stops. At least with the Diesel I can get to truck stops and not have to worry about height restrictions. I agree that $1000 and up is too much for a gas tank on a 12 year old truck. I looked at portable ones and most of them don't look wide enough for the diesel can. I decided to just get a couple of these and then if I stop somewhere I can just top off the truck tank.
