IMHO you have two problems. Having your cargo get wet, and having water leaking into a steel tube airplane.
I believe that the FAR's and CFR's and FAA ASI's and DER's and most of the experienced people here would agree that you can apply commercial weatherstrip to the door the same way an owner can paint or upholster a
non-commercial airplane, using any good quality weatherstrip that does not require modifying the airplane.
To me, this is more of a damage prevention and maintenance issue than a wet sleeping bag issue.
If anyone asks you about the weatherstrip, tell them you are... "taking non-structural, preventative, owner-maintenance steps under Part 43 to insure the continued airworthiness and safe operation of your aircraft, which is also in direct accordance with the FAA's recent paper on continued airworthiness concerns for the aging GA fleet".
I can't remember the official title of that FAA paper, but it was within the last 5 or 6 years, and was jointly written by the FAA, EAA, and several type clubs as a cooperative position paper.
Basically, put in self-stick rubberized foam weatherstrip of the right thickness. Use "closed cell" foam and not the cheaper open cell foam which can hold water.
