Actually, in the plan view it hangs off of both sides of the A-frame tongue, spanning about 1/3 of the width of the 8 ft wide trailer, or about 32". It is still tall, with about the same proportions as a 20-lb tank, but 2.6 times as big in every direction, or maybe just a bit taller/narrower. You can see an example at Manchester Tank (that one is 30" diameter by 54" tall overall).
Sorry, didn't mean to derail the thread... just thought the contast was amusing!
