There is an old saying, "just because you can, doesn't mean you should." The green
propane bottles are considered "disposable," not "refillable." You MAY be able to refill, but there's no guarantee to be leak free. The only way I'd ever transport a refilled green
propane bottle is out in the open. Not in my trailer and not in my tug. I have friends that nearly lost their 5th wheel to refilled green
propane bottles being transported in the "basement." Toooooo scary for me. I'd get a 5 lb. made-to-be-refilled propane tank and be safe:
