I am looking to install a 60 gallon RDS gravity tank in back of my 2015 chevy 3500HD dually. Looking for some answers before purchasing.

1) can you fill your main tank as you drive
2) will it stop filling when main tank full automatically
3) does truck have a problem when fuel gauge always reads full until RDS tank is empty.
4) Do I add a fuel filter and water seperator(any suggestions.)

Thanks for the help

1. Yes
2. Yes
3. No
4. I did not. The fuel still runs through the OEM fuel filter.

I love my aux tank. It is nice to stop when you want to stop vs when you need to stop. I would get an aux tank again,

Have there been times where I wish I had the full bed? Yes, but there are more times when I appreciate the extra range.
