what about this gas caddy?

[Right Touch]

this is in response to the previous thread about the gas caddy. Ive been looknig at this one and others similar but they arent rated for trailer use. Seen one guy have it strapped in an enclosed trailer. Seems user friendly with the wheels for rolling and filling and the pump action rather than gravity fed. Heres pics of both this one and the alternate. Your thoughts?

just another note: the red one is 30 gallons and they have smaller sizes for mix. Your intial cost would be more to buy two of the red ones but seems like the better option for an enclosed trailer.
