I have done the cut and splice on both tanks on the truck and on one of the cad's...it makes it a heck of a lot easier to connect/disconnect, and you get the satisfaction of being able to actually see that everything is in place.
Pulling the bed would be the next best thing, but the truck barley fits in the garage right now, and the HOA would kill me if I left either the bed, or the truck without the bed in the driveway for more than 5 mins.
