I live in a 91 manufactured home (trailer).I plan on puttin a 180 gallon in my kitchen .the floor joices are spaced 16 in apart and they are 2x6.There is also a large black beam under those goin across which what i saw when looked under my trailer.the beam was about 3ft from the wall.my ? is would my floor hold the tank if i put it going across the floor joices.i couldnt really seeing the difference than putting a 180 upstairs in a house.
