Is it possible to use the rubber pigtails from the main branches up through the floor directly to each appliance.

I would put something over the exposed hose under and through the pan and floor.

piping penetration, etc

Lipets,
Newer airstreams use what appears to be ABS plastic about 1/8" thick cut like a donut with the hole in the center and split for installation around the pipe; then pop-riveted to the belly pan in 3 places; I copied this idea some years ago and it works well. I have the best results using low expanding foam for sealing (the white stuff) where the plywood floor is penetrated to avoid a mess and trimming; duct seal works real well too as suggested already but is not always completely rodent proof. Double flaring tools are readily available nowadays and a lot cheaper then they used to be.

I use adel style cushion clamps to secure the lines because I have them for the race cars in the shop; (the way airstream did it in the old days) but the nylon clamps work well too; I recommend only colored nylon black or grey for longevity. Another source/option for clamping is hydraulic line cushion clamps at the industrial hose and fitting shop; most however require 2 fasteners rather than one.

Be sure to use fully annealed new gas line tubing; old stuff may crack unless annealed first before flaring because it does work harden slowly; kind of a time sponget o do annealing and clean up the scale inside the tubes though.

My Caravel only had one shut off valve underneath; for the water heater and I left it there; all other valves (heater, fridge,stove) were next to the appliances where it is more convenient for servicing.

The only time I ever experienced damaged gas lines on an airstream was a trip on the Alcan in the 60's when it was mostly still gravel.

The piece is a standard issue Mobile Home or RV plumbing part. It is more like a split flange than a donut. It may even be available at you local home center in the plumping department.

entrance flange

Lipets,
Wahoonc is correct, you can buy these at the RV supply, but I just made my own using abs scraps from the local body shop ( old bumper cover pieces), cutting them with a hole saw, enlarging the center hole with a unibit or drill bit to the needed diameter; then cutting into the two halves with tinsnips thru the centerline. This is the way rural folks do things at times to save a 50 mile trip for gofers.
The bumper ABS will likely hold up better than the plastic used in what the RV shop sells. I took a picture of the neighbors 1992 unit because it was easier to get under and you can see this one is cracked/deteriorated somewhat and used sheet metal screws to secure; both methods work. The purpose is to keep the critters out and avoid metal to metal contact.

LP pipe leaks ?

hi I am new to the Airstream Trailer, just got it home yesterday, 1980 Excella II 28 feet. The seller advise to have the gas pipe check before use any gas operate units (stove, hot water, etc.). I call plumbmer yesterday ask them if they will do the test and fixed it if nescesary they told me they dont do that type of work. I am not experience enough to towe the AS to get it fix. Is it away i can do the gas leak test by myself?.
thanks
boon.

Spray all the fiiting with soapy water or windex, if it leaks you'll see bubbles

There shouldn't be any hidden connections so do all you can see.

Just like you have a smoke detector in the house, lso install a gas detector inside your trailer but low down.

thanks bob., I will give it a shot. I have the AS for couple days now. I am very happy with, but it just so many you have to learn. I am in process of put up the 30 amps outlet on the house to connect the AS to the power source. I next thing is to out all electric, then may be the plumbing next.
thanks
boon.
