Propane tank location? Ideas!!!!!

[Highway Yacht]

Don't most of the gas appliances in a conversion run off the propane "vapor"?? I was under the impression that just about all forklift ran off "Liquid" propane.. I know when I checked with a tank supplier about using forklift style tanks, I was informed that they would have to be converted over to vapor which would cost as much or more than buying a suitable vapor tank in the first place. Don't know if this is true or not... anyone know for sure??

If engine heat is a problem for Propane why do the forklift makers mount the tanks on top of the engine on the hood ? mine was mounted close to the engine compartment and never vented and I live in AZ also,you guys never saw a farm tractor with a 100 gal propane made into the hood setting on top of the engine ?
FWIW that is the reasoning behind the 80% fill on propane tanks to prevent the venting from heat 

good luck

I don't have any horses in this race because I decided long ago propane wasn't worth the risk after a friend had a bad accident with it in a collision. A personal choice! not to force on anyone else! Opinion it should be in a area with as much protection from a impact as possible(inside frame rail) etc.  Be where a mechanical leak can vent thru bottom(lowest spot)Be away from source of ignition (battery compartment etc.) Be careful and do it your way.  If I repeated my self just be careful.  Bob

One has to probably assume that more house fires are caused by electrical problems more so than issues with propane  Bob. It's just a matter of choice. People get killed hanging Christmas lights that could have been saved if only they had been grilling burgers on their propane Weber's instead. One never knows.

I agree Scott. Just a personal choice. Guess I'm lazy. Smooth cook top stove. Elect hot water heater. elect heat.  Actually have found my total electric coach to be more cost effective than my friends combo (lp/elect)s&s by far while wintering in Florida.   Bob

I read in the FMCA book only a small percentage of RV fires are caused by propane and they were from poor maintenance even the fridge fires most are caused by electricity 12 v or 110 they have it electrical as # 1 cause for fires 2 was under inflated tires propane was the last on the list and are very preventable with proper maintenance same with the tires

good luck

Propane, like electric, is dangerous. It all is, even driving a bus is dangerous because of the crumple zone. We use what we use and take the needed precautions. I like cooking on a gas stove so I will be using propane, I have a suburban heater and water heater and probably will be getting a 3 way refer. Propane is a choice, like everything else. The placement is the issue. On my Jamboree class C they had it on the passenger side in the compartment behind the front tires. Im not sure propane or batteries, should be placed near the exit door of our coaches, nor in the front nose, nor in the engine compartment..... even behind the tires I question. But where is the safest place? Im not sure....

" People get killed hanging Christmas lights"

Scott,

Good thing those lights weren't powered by propane or they would be double trouble.

We have ours 23.5 gallons fixed across about 1.5 feet in with a 3/4 ply box around it screwed and glued with a removable top in the wet bay. right in front and between the wheel-wells in back with the letters "LPG" on the door side of access  to it with the filler fixed in the outside siding.

All of that is true.   All tanks have void that is dedicated to expansion.  They also have a overpressure vent and my vents are threaded so that I could attach a hose.  As a general rule of thump, propane tanks "should" not be mounted near a heat source and be away from batteries.

Fork lifts are a different animal.  While we us propane as gas, a forklift uses it as a liquid.  Even our tanks get cold and can even get a frost layer.  The forklifts, in heavy service, can freeze everything.  They use hot engine coolant to heat the propane in the carb and the pipes.  Their tankl also gets really cold so mounting it "near" the heat source is advisable in that case.  Didfferent situations, uses and rules.

I think the logic of the reg about running the vent to the rear is that if it vents and you are underway then an ignition of the venting gas will pose little threat at the rear.  I am groping for the logic in that.

I have seen a RV destroyed by a propane line rupture.  According to my friend, he was standing in the living room of a old 26 foot S&S.  He heard a whooump and turned to see flames coming from under the sink.  The sink was across from the door and he said he dashed out the door after taking no more than three steps.  Flames singed his back and hair as he jumped out.  He was certain that if he had been a mere few feet further from the door he would not have made it.  he said that after running maybe 29 feet away he turned and saw to his horror that the interior was an inferno.  it took seconds. Propane is extremely dangerous.  There are a lot of regs and they are pretty anal about every little detail.  it is because of this fear and respect that we have so few tragedies with the stuff.  Be careful.  Find out what the rules are and follow them....to the letter.  It isn't really relevant if you don't understand why a reg is there or how many folks you have seen get away with doing it another way.  None of that matters cause we tote some precious cargo around and we need to make sure we give them the very best our efforts can provide.

I have propane "everything" and I wish I had had a propane fueled generator.

My very best wishes for your safety,

John

Propane is a liquid in all tanks JohnEd you stand a forklift tank upright it becomes a vapor tank

I did some reading online from the NFPA and found interesting details like the restraint must be 8 times the weight of the tank. Something to that effect. They want the tank secure in the event of impact. Another interesting point was no propane forward of the front axle. That makes a lot of Olympian heaters non-conforming. Had a lot of detail about venting the compartment too.

There is no intent on being judgemental, I use propane. Just points that may help others.

  Just toured Colaws RV Salvage yard in Carthage MO.. After walking around and through many the wrecks, and seeing the various forms of damage, the last thing I would be afraid of is propane. Saw a Big Newell with obvious rear end collision damage, looked like the engine caught fire and set the whole rear end ablase. Many others also appeared to have both collision and fire damage, so if your building a conversion think about that.

   I watched a brand new class A catch fire and burn to the ground, and it was due to an electrical fire. It was parked on a lot and lit off all by itself with no one around. There is no safest way, or best way with these things, there is only the idea to follow common sense and good engineering practices and following codes as close as practical, but even in the best built homes, accidents can happen. The safest RV would have no electrical or gas system, and no engine. And it would be utterly useless. So regardless of what you use, or how its built, always have a fast way out.
