Before you do anything else, please take the time to visit a CAT or other certified scale to verify not only your current overall weight, but also your specific tongue weight, axle weights, etc.

Also, please take a look at some of the videos in this thread. I can't make your decision for you. But, I would be very cautions about hanging something as heavy as a dirt bike off the back of a conventional travel trailer. That much weight to the extreme rear has the potential to drastically reduce tongue weight and possibly create a sway situation.
