Knowing full well the feelings of many on this board regarding the use of propane, I have a CONSIDERATION, and only that, regarding the possible use of the fuel in our conversion. The wealth of professonal knowledge and experience of the participants of this board prompt me to address a couple of "what if" questions prior to taking my questions to a local "professional", in the business, who might be possibly more concerned with sales than with safety. All that said, please allow a little background and a couple of questions. We have a Crown Highway Coach, 10 wheels, midships engine pancake style. Roughly behind the engine area, we want to putstove/oven on one side and hot water and fridge on the other. Problem comes with the fact that there is a lot of engine heat, the exhaust system, transmission and the batteries in the immediate area.under the floor It is not impossible to go across with pipe under the floor, but the obstructions and aforementioned make it questionable. This would allow me to place two tanks in a bay directly under the door side. Also considering two propane tank setups. One in a bay directly under the heater, water heater and fridge. The other a tank setup in the huge rear bay (trunk) running black pipe about 20 feet on the inside of the coach, (above floor level) for the cooking facilities. I cannot run a pipe on the other side due to shower, etc. Questions: 1) does anyone have any knowledge (experience) of problems or code in running a pipe over the engine and exhaust system, (three or four inches away from any contact and open to the ground below) and 2) what code or practical problems might we run into in running pipe that length inside the coach, in a chase? (Ian, are you listening?  ) Many opinions out there I am sure. Thanx in advance for all input. RCB | ||

hey rc im doing the same thing with my black pipe to route the propane witch i have no problem using for heat and cooking i have a crown also and i dont think you will have any problem running the pipe aon that side of the coach i think you have a turbo on that side but your pipe has to be a foot to 16 in away from your exhaust if you put a shield on the pipe dont see where you could have a problem im putting three 30lb tanks in my spare tire compartment all going to a manafold to the black pipe witch will feed the stove and the heat as to running the pipe in a chase i would consider some inspection points to check the pipe periodically i tell you what compared to to some of the installations ive seen in comercially built trailers and wood and aluminum so called coaches alittle dillagence? even a semi skilled can come up with an equal to or better system | ||

Hey R.C.; If you put your mind to it, anything can be done. With my 1974 Crown 10-wheeler, I am going to exploit that huge rear trunk by installing a second 100 gallon fuel tank along with the large diesel apu. A second string of 12 T-105 batteries are planned for right behind the rear drivers. Will have to relocate that small rear air tank and rubber air lines to the rear tandem brake cans to make room. Of course this means the main frame rails will have to be extended back and down and into the rear trunk to support all of the forementioned weight. Planned right now on bolting it on. Why not consider placing your propane tank stuff in the rear trunk? That would be quite a ways from the radiator, mill and tranny and if the exhaust system was reduced, a long way from the muffler also. I am planning on relocating the starting batteries to the other side of the block alongside the oil pan and actually having the air cleaner inside the kitchen base cabinet INSIDE the coach. This is because the plan right now is to update my big cam 855 250 non turbo Cummins into either a 400 or perhaps a 444 model with a turbo and intercooler. Interesting turbo plumbing to say the least. Anyway, the mill mods include a short muffler dumping right out of the turbo with the exhaust dumping out in front of the driver's side tandem. You can do this also without a turbo, thus freeing up the entire rear trunk for your propane stuff. Good luck and...CROWNS FOREVER!! | ||

- I dont know of a code pro or con to your particular install question. I would certainly install a heat sheild. - I dont think you can have a problem running inside but I suggest running only the least amount of propane piping inside to the equipment, run the rest under, outside. try to avoid storage compartments but better than inside the coach itself. Now I am not dumping on your ideas or on use of propane but a lot of people travel with the propane turned on, especially in the winter when it is cold so run it as safely as you can. Have fun - cd | ||

Here is a partial quote of the code book concerning installation. 1192/5.2.3 (c) Tanks mounted between the front and rear axles shall be installed with as much road clearance as practical but not lower than the front axle height. Tanks mounted behind the rear axle shall not be lower than either the rear axle height(excluding differential) or any section of the frame immediately to the rear of the tank, whichever is higher. 5.2.6.1 Compartments shall be ventilated at or near the top and at the extreme bottom to facilitate diffusion of vapors. The compartment shall be ventilated with at least two vents having an aggregate free area equal to at least 1 sq. in. for each 7 lb of the total LP-Gas fuel capacity of the maximum number of largest cylinder(s) that the compartment can hold. 5.2.7.2 The manual control of the tank's shutoff valve,,,shall be located not more than 18 in. from the vehicle's outside wall. There is a lot more, but that should give you some ideas. Code book is ANSI A119.2 NFPA 1192 Standard on Recreational Vehicles 2002 edition. Bill |
