gotta drop the tank home boy. sorry. its easy tho. get afew people to push it onto ramps in the back and its like 4 bolts? a plug for the sensor and the lines.
Drop the tank? Can't you just remove the parcel bin and then its right there? 4 bolts and a couple wires, the you pull it right out?? I can't see any reason you need to drop the tank...
