Yes I agree about lots of possibilities. You say long so I assume you are talking about a 27 to 31 ft. model. Do you have any idea what year and floor plan it is/was? Where is/was the toilet?
Are the two or three holding tanks still aboard?
You ask about interior walls. Is the inner skin still there at all?
Is it metal or wood? Has the wiring been removed?
Lots of considerations. I always think of prices in Alaska being higher that most states, but depending on answers to what I asked I have to guess a value somewhere between 500 and 2000 dollars for the shell,continental UsA.
Tires 100 each, axles 1000 each, HotWaterHeater 400, Furnace 500??, refer 300-1800, just a few ballpark figures.Air Cond. Not needed
Cabinetmaking skills would be a real asset. Patience an even greater one. Electrical skill also necessary or contractable.Sheet metal experience a real plum!
Lastly any interior builds need strength at minimum weight, with just a bit of flexibility built in or at least expected after a few 100 miles. And remember that the upper walls & cabinets have that curved line so plumb is a whole new 'dimension'.
Now if its to become a parker-only plans could be a bit different.
There are surely some amazing success stories I have seen on the web. No reason yours can't be another. Good Luck and don't be afraid to ask anything, and don't get discouraged if there is no immediate answer.
Oh yeah and don't fail to take pictures.
