High Pressure Line

[JohnandLeann]

Our old 94 coleman does not have this high pressure line that some of you speek of.
Would it be very difficult to put in a hard line from the tank to the side, area, of the camper where there is a regulated connection for the inside cooktop when it is used outside?
Run it along the inside of the frame and put a hole in the side wall of the frame or attatch it to the under side of frame?
I would think that I could "T" the line before the camper regulator and run the line from there, to the spot where I want to have the unregulated outlet.
I already run my Coleman Duel Fuel Campstove from a second bulk tank that I bring along.
I split this tank with a propane tree and run the lantern from the top of this and run a hose inside to our Mr. Buddy Heater through the place where the regulated hookup is, and run the camp stove from another port on the tree.
It would be nice to just leave the tank on the camper and not have to lug around a loose tank. We dont use the inside cooktop or Mr. Buddy from the camper reg'd line. Just does not seem to have enough presuure to even boil water. Campstove cranks from the propane tree.
 
Thanks for your ideas and solutions,
John

What you're describing sounds pretty much like the way my 03 Fleetwood Cheyene is set up. The tank has a tee, and the unregulated leg goes to the curb-side of the trailer. Attached to the trailer frame where the outside stove attaches is a high-pressure connector. The other leg of the tee is regulated and runs to the water heater, furnace, and fridge.
If I were going to do this, I would make sure that the new line going under the trailer is above the frame and well supported so that it doesn't hang down (or fall down) where it can be snagged & sheared. Also, use good quality connectors and check for leaks. I don't have any pictures, or I'd post them so that you might be able to get ideas.
My 2nd hand Pup came with two tanks on the tongue. Only one is connected at a time. I like this because we are not heavy LP users. So when we run out, I've got an extra full tank ready, and I can fill up the spare at my convenience. Since you are using both tanks anyways, why not just use the regulated one as is, mount the 2nd one on the tongue, and use it as your HP one? You could still permenatly mount a line to the side of you Pup, then tee off that for the other services that you want to attached.

Please don't confuse regulated low pressure with low BTU.  :eyecrazy:
Your 'inside' stove is so designed (derated) with little output.
A CampChef stove (that can connect to a PU low pressure connection) puts out 30,000 BTU/burner and puts to shame the 10-12,000 BTU your camp stove puts out!

You can certainly do what you want to do, either permanent or using Marshal extend a flow tees/kits. Some Colemans come hardwired with a 16 psig regulated high pressure port on the side of the PU for their 16 psig stove.
