dual use tank gas and oil ? OPINIONS wanted

OK looking for opinions on would it be worth trying to have/make one . I know oil can get hot (300+-) so thats a factor . THe oil tank would be front and low , gas high and in the back of the tank plus all aluminium . If you can't tell im building a cafe
Thanks

The oil and gas will have to be thermally insulated from each other. Hot gas will not work. Jim

I saw this one at the Brooklyn invitational earlier this summer
