Julie, I hate to pop your balloon, but I don't think your Honda can SAFELY tow that Trailmanor. When you try to figure weight, you've got to add propane, anything you're going to carry, food, water, the passengers in your car ... it adds up quickly.
There's another website that discusses this at length (PM me if you're interested). Many people feel that to be safe, only tow 80% of your vehicle's towable "allowance". If you go with that rule of thumb, you're tip-toeing that line. Also, your Pilot is definitely going to feel that much trailer behind it, and you may not be able to add sway control to your car. I have friends who tow with the Honda pick-up (can't remember its name), and to add sway control would void its warranty.
Again, I'm not trying to sound like Ms. Gloom-and-Doom, but I'd be really, really hesitant to tow that size trailer with your Honda. Good luck!
