Joe, as you most likely know each installation is different and thus the results may vary but it appears that your site is a good one for the install you described. The buildings and trees should not be a problem.
If you use THIS LINK and are patient enough to follow the links in the threads you will see the details of the installation and test results for my system.
My transmitter is a home brew unit which provides 86 mW output to the antenna system and uses a base loading coil at the antenna. The difference is that the AMT 5000 has the loading coil integral to the transmitter but the performance of these should be comparable.
The most critical thing is to make sure the antenna system is resonant. Resonance is very sharp and is easy to miss.
Based on my experience and providing the background noise level is reasonably low you should easily get 1 “car radio” mile range and maybe more.
