Jonathan you be looking about 8lbs per gallon that will give you around 450lbs give it or take (you better start eating a big breaksfast for now on lol) what you can do is get two containers .fill one up on the truck when you get to your garage drain the one on the truck to the one in the garagage (gravity feed or a small pump). If you gonna do it for sure lmk , i might be able to get a 55 gallon container ,we can split cost to half .
