ANSWER: The VH-Sport RO is the best option. It has a 600 lb total carrying weight and a towing capacity of 3000 lbs.
You will also need a bigger Class IV or Class V hitch that can support the combined weight of your bike (est 536 lbs), VH-Sport RO (111 lbs) and the Tongue weight of your trailer. Also Coachmen frames sometimes do not extend far enough behind the Camper. The hitch may not support this weight. Check the hitch mount carefully.
