Kathy,
Congratulations!
Having been kept under a roof all its life is good.
Be aware however that over time the putty that creates a watertight seal around windows, doors, edge trim, roof vents, etc, will dry out and shrink.
When this happens, water will begin to creep in (un noticed

) and by the time you realize there is a problem, the water will have done a great deal of damage.
Remember, it has to soak the faming inside the walls/ceiling before it ever reaches the backside of the paneling, then on to the interior.
I offer this not to scare you, but to make you aware that most owners do not realize how this process works. There are many horror stories out there from people who bought a perfectly preserved trailer, then parked it outside without ever considering that the regular maintenance that had been deferred all its life really needed to be done the minute they bought it.
Within a year, or even months, it was ruined by an un noticed leak(s).
When the putty seals dry out, smearing caulk all over the joints will not fix or correct the problem.
The trim, vents, etc. need to be removed so the putty can be replaced.
Any competent repair person or shop can do this work.

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
