I have tapped into the gas line for Olympian heaters at the stove twice. In our Intruder we had an "L" shaped kitchen, I drilled a hole at the floor thru the end of the cabinet behind the couch. The heater was mounted on the face of the "L", with a shutoff behind the couch. Our present Phaeton doesn't lend it's self to a mounted heater. Again I tapped the line before the stove with a "T", then ran a LP hose with LP ball valve and quick disconnect (QD) under the sink, which is in a slide. I then drilled a hole down thru the cabinet floor (on slide-out) exiting at the toe kick of the cabinet. The Olympian heater equipped with legs is attached to a QD 12' LP hose that is placed under the toe kick of the cabinet and the fascia of the couch. I plan for the Buddy heater's LP source again to be a "T" at the stove with hose access inside the sink cabinet or the rear seat of the dinette with a QD and valve. A 6'-8' LP hose with 1# cylinder adapter will attach to the heater. The "T" is nice to use since a simple cap at the "T" will make easy removal of the hose, valve and QD when the RV is sold. I use only prepared end LP rubber hoses, rather than flared copper tubing, so any vibration or corrosion can't damage the lines as with the copper.
