Don't use the crash bars to strap down your wing. They are not intended to withstand tie downs. What you need is 2 pair of ancra nylon straps. They are about 8 or 12 inches long. Loop one each around the triple tree which is up under your fairing about headlight level. Then strap that to the front two hooks in the camper. I usually collapse the front forks about 1/2 to 3/4 or until I feel it is snug enough. The other two straps are for that one time you go camping and forget to take the straps off your bike. It'll happen sooner or later.
I use a mount-less wheel chock that I got online. It has a rubber mat under it that slides off under pressure. For that reason, I got a long rubber mat at Menards (sets you back about $75) in the carpet section. It is very heavy and it is also thick. I lay that out where the bike will ride and pull the bike in on top of it. You can cut it to fit your cargo area.
Then I cinch the bike down (don't forget to raise the kickstand when you get it tied down). I then take two more ratchet straps from the wheel chock to the back two hooks in the camper. Nothing moves after that.
You can optionally put a strap through the back tire to keep it from moving but I have never done that and it has never moved.
Keep in mind that in the 19RR your bike will be close to the stove when it is upright. My father had an incident in his 19RR where it hit the stove and turned the burner on while they were traveling. Luckily, all came out well in the end. He now doesn't travel with the gas on but I still do if I am travelling long distances as I usually have the fridge stocked.
That's how I get the wing strapped down and have had good luck in following those steps. I really loved my 19RR for those rallies that were at state fair grounds. You could pull in next to a power pole and have a great little camp set up. The trailer pulled great with the wing in it. What I didn't like about the 19RR is having to walk all the way around the bike to get to the bathroom or get a cold bottle of water while traveling.
is the wheel chock I use. Sadly you can't buy the size for the goldwing anymore (near as I can tell).
are the straps I mentioned above. As stated carry spares. They are cheap enough.
I hope that helps you out.
