no more horizontal propane tank for me

I wanted a standard grill propane tank when I bought my camper new, but it wasn't available. So when the original needed to be re-certified, I decided to change it.

Here is the almost end result --


First, disconnect the propane output.


Which is behind the stove.


Stove out - propane disconnected.


I think this could use a couple of large washers (and caulk).


I think the tank container will come out.


Everything out -- nothing destroyed. Now what?


Cut a hole big enough to tip in a vertical sheet metal box.


Prototype for new sheet metal. Not going back now.


Fits -- went back in the same way the original came out (almost).


Tank fits too (can't use that one of course).


That much room for a replacement short drawer, and a decent size compartment - with a new cabinet door.


New box. May have over-paid for this, but he was close, did an excellent job, and was the only one that gave me a price.


New box installed -- except for support for the bottom.


Removable support -- in case anyone ever wants to take it out.


Use up the rest of the propane in the old tank.


Pressure test at 20 times the nominal pressure. (don't try to pressure test with the regulator in the system).


Ready to go - after I reinstall the door, and a little simple carpentry inside to shorten the old drawer and use the new space.
No change to the camper frame or skin.
  • Thanks for the comments.

    I thought some would mention this. Here was my thinking(?):
    1) the inside of the case is effectively outside the camper.
    2) there is no leak in the case (verified) - except when I deliberately disconnect the tank, in which case the compartment door is open.
    3) there is no ignition source in the case (dangerous to assume never)
    Therefore, very small and acceptable risk, and if you never hear from me again ---
    On the other hand, I can't think of a reason not to put in a vent tube from the bottom of the case leading outside -- when I find something appropriate. Has to be impervious, or else any leakage would be right into the camper. Such a vent would also take care of condensation.

    It was easy -- put the box on it's side, slide it in, tip it into place.

    That's some wood braces (not shown) for the right side and front. No sliding around.

    What are those two 4 inch ducts for? (In picture #8)


    In an Outfitter Apex it's the heat ducting to the basement.
  • Great Job,

  • Pretty sweet mod.

    Make sure the bottom of the new box is sealed water tight because the tank will have condensation running down it if used in humid areas. Plus a blowing rain will sometimes get in through the door vents.

    Only thing I see wrong with it is I would have to add at least one small vent at the bottom of the compartment to ensure any leaked propane can drift out. The way it is now, there is the potential for a pool of gas in the bottom of box which could be a hazard. Granted it's a slim hazard, but still there and why manufacturers don't do this at the factory.
  • Nice,
    From here it looks like it would have been, ah, 'entertaining' seeing that new box go in.
    I also want/need to do something simular but battery box, enlarge and sliders.
    Almost no aftermarket for compartments or boxes.
    Good work.
  • Nice job, I'd like to do the same to my Apex 8 someday. Could you have used the existing box but re-oriented to vertical? --- edit DUH, my bad -- that won't work at all! phhhht! Brain fart
  • I like your ingenuity!

    I too have horizontal tanks and while the regular #20'ers are convenient, I will deal with what I got... even if it means guying new stock replacements.

    Nice job!
  • Did your horizontal tank had a gauge?
    I don't see bottom vent holes on new box?
    I like mine for the feature and went the other way, replacing vertical tanks in Lance with single horizontal tank.
    That leaves me lot of space to put BBQ, wood boards and charcoal on top.
