Dirk,
It might work okay, probably much like many of the concoctions developed over the years to waterproof cloth.
Trailers used a special dope similar to that used on aircraft...it was the best they had at the time.
We've come a long way since then...
Using a proven modern method/material will likely give you a lot longer period between the need to re-apply.
Another home brewed concotion I tried a few years ago was Silicone and mineral spirits.
I made a canvas bathtub (foldable) that needed to be very flexible so it could be folded up and stored.
The trailer didn't have a bathroom, or tub/shower, but it did have a kitchen sink with hot water.
Mix clear Silicone caulk with mineral spitits (odorless is much better) until the consistency of thin paint, and brush on.
A couple coats did a good job.
The tub held several gallons of water, and me, with no leaks.
It would probably work on the exterior of a trailer, but it may need to be re-coated pretty regularly?

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...
