I bought a used Patrol recently, and I have not needed to pitch it down tight as of yet. Its fairly easy to enter/exit when pitched in normal mode.
I had concerns about condensation, with the front beak and closed rear, but I haven't had any issues, with this.
If I get a chance, I'll set it up in the yard and give you a measurement on the front beak, with it pitched down tight.
I've only been through one or two rain showers with the Patrol, and stayed bone dry, although, there wasn't much, if any wind.
