One way to test an antenna with a low power radio that has delicate finals is to use a resistive SWR bridge for testing.

In need of antenna advise for HF N3REN 1 week, 5 days ago
Here is a site that describes what happens when you bend a dipole.

If you can use an antenna tuner the March 2016 QST has a multiband dipole that is just 48 ft across and covers 10/20/40 meters.

I'd suggest a "fan" dipole for 20 and 40 meters, You could use the two trees to support one half of the dipole.
The 31 ft mast for your vertical may be able to support the other half of the dipole. 15M may load up just fine with a tuner.
