Does anyone carry a 20# propane tank on a trailer hitch carrier?Didn’t, think it was a good idea. Saw a small C parked at Wally World with tank and other stuffed lashed down. Worse part, carrier looked to be modified or home made.

I do not, partly because I don't have a hitch-mount cargo carrier (aside from a bicycle rack), and partly because my RV has a built-in permanent tank.However, I think it a not very wise idea to carry propane outside of the limits of the structural framework of the vehicle. If I'm not mistaken, DOT regulations prohibit mounting propane tanks such that they extend over the bumper or under the frame, though I don't know if that applies to portable cylinders or only to permanent tanks that are "part" of the vehicle proper. In any case, the potential for bad things in a collision should be pretty obvious, even for an otherwise comparatively minor one, and it's not a chance I care to take.

carrying plastic or metal gas cans, generators, propane tanks on the back of a trailer or RV sends shivers down my spine. Nothing for protection against a fire if someone rear ends you.

Was it a legit camping rig or a motorhomeless?Just because you see it, don't mean it's right!That said, the paranoia, rumors and wives tales about propane on this forum would lead one to believe it may essplode if even dropped.Truthfully, they are very hard to get to essplode.Or think about it this way, how many 20lb propane bottles are there in use today, jsut in the US? I have no idea, but theres 44 million single family homes and 8 million RVs in the Yew Ess of Eh. I'll call that a round number of about 100 million propane bottles in service + all that are used in commercial/work settings.Whatever the number is, it's uuge. How many have exploded that you know of? (Personally, no internet allowed)And of them (likely zero anyways), how many actually exploded in a fire ball and didn't just BLEVE or rupture and dump gas?Is it the best idea? I'll go ahead and give a hard NO. Is it "that" risky? No, not really.

Would I, no. Is it super dangerous, probably not. Here is a picture of a 1965 Ford B that was owned by a friend when it was rear ended by a semi in 1974. I ended up buying it and had a body shop put the body back together for our first real RV that isn't just tarps over a pickup truck. I did not put the tank back on the back. The inside was all ripped loose in the crash so I made the inside the way we wanted. The LP tank and tire took a lot of the impact. The LP tank was still sitting in the corner of my Dad's shop when we sold the place in January 2020 and was still holding propane.

Well they can explode. Couple years ago just South of Sebring Florida at a Propane Tank Storage Facility they had a fire and some tanks we found 1/2 a mile away after they exploded.
